Going to look on Janis lol! *[HCV-RNA (qPCR)-negative] is defined as less than 100 copies/ml of hepatitis C viral RNA as measured by the National Genetics Institute assay. Keep in mind, different labs do the PCR test differently. There is no set protocol for this test as of yet so results vary from lab to lab.

Its a so called borderlineresult.
Your friend was probebly tested with taqman test down to >15 iuml the only test they use where I`m from. (Sweden that is)
Its a good result but can indicate that a extended treatment should or could be in the the tx strategi plan if geno 2 or 3.
Hugs to you Lady L

So it sounds like congratulations are in order. Check the limits of the specific test.
Good luck,
Brent
Detectable but <15 is not UND but darn close, so it is up to your friend to decide which side of the border of extending tx or not he or she wants to stand on. (Unless your friend is a geno 1, of course, in which case such a test result is fantastic at week 4.)
It's a Geno 2b-er. I'd figured it was dam close so probably UND by week 5, which really doesn't call to extend, exactly, right??? Week 5 is so borderline, ya' know?
They really can't extend either, labs falling, no rescue drugs, etc.
I get soooo peeved by Dr.'s that don't do enough VL testing!!! If this was me, I'd want another at 5-6 weeks to know. Most don't do it again until week 12, what IS up with that?
Thanks again mucho! Looks like I was wrong in thinking that is UND.
LL
Who is who is it you or your friend thats geno 2 or both probebly both since both = 2, or was it a it that was 2b

Lauri may be talking about my result which I've shared with her and 'comeagain'.
I'm a 3A Baseline VL 262,000 and just got the print out of the test - it is still detectable - the specialist and doctor say 'it's as good as UND' , maybe because I don't have right of extension (well, I'd have to really fight for it privately even). I do realise it's a good result and I'm responding well to tx.
The form says as follows (so it looks as though still detectable but small):
HCV RNA : < 15 IU/ml
HCV RNA: <1.18 log IU/ML
'this result was determined using the Roche COBAS Ampliprep/Taqman HCV test which has a linear range of 43 HCV RNA IU/mL to 6.9E+7 HCV RNA IU/mL. Note: Results are expressed as the number of HCV RNA IU/mL and the logarithm of the number of HCV RNA IU/mL'
I've been waiting to post Dr D but always full; my specialist said 'virtually almost undetectable'. I know Zazza and many of you would advise me to try to extend. Quite frankly, I don't want to think about it right now, and have got a little time to build up my case now with the private gastro.
Thanks all for your assistance, and pushing me to get this PCR done. Much love and hugs for all the encouragement :-
Now.. you might want to request a lower sensitivity quant PCR just to be sure .. I've been okay with my <15 IU/ml sensitivity holding from Week 6 and I'll see how I feel as I go, if I want a lower sensitivity than that.
However...looks like you're UND at Week 4 to me.
Trish
Your friend really has to get his/her own copy of the test results, which would include the name of the test taken. If you then post exactly what the lab report says, it should be easy to figure out whether she is UND or not. As posted, I really wouldn't even venture a guess.
Now with that said, as previously mentioned there are dual range qualitative/quantitative tests. I was in a drug trial that used this type of test. It's quantitative limit of sensitivity was 30 IU/ml. In other words it could only provide a numerical value for your viral load if your viral load was 30 IU/ml or higher. Although it could still qualitatively detect the virus down to 10 IU/ml. But it could not give you an exact number if you were detectable between 10 and 30 IU/ml. For example:
If you were below 10 IU/ml, you were UND and the reported result was "<30 IU/ml NO HCV RNA DETECTED."
If you were detectable between 10 and 29 IU/ml, the result would be "29 IU/ml."
If you had a viral load of 31 IU/ml, it would say "31 IU/ml." if you had a viral load of 81 IU/ml, it would say "81 IU/ml" etc.
Confusing? Ambiguous? Retarded? Yes, but in the infinite wisdom of the lab dork shut ins who come up with these reports, this makes perfect sense. The only way you're gonna know for sure is to confront your doctor and preferably call the lab yourself and get to the bottom of it one way or another.
I tried to "Google" the test, but got conflicting results and apparently this is a test more popular in your country than ours.
I'd like to say that your doctor's are confusing you by saying "it's as good as UND" because that's a very confusing way to explain things to a patient. You are either UND to the limit of a test or you are not. That should be clarified by your doctor 100%. If indeed the limit of the test (as I suspect but am not 100% sure of) is indeed 15 IU/ml, then you are UND. Period. For all practical purposes 15 IU/ml is a pretty sensitive test. My advice is to try and get this clarfied byyour doctor, and if you feel your med team isn't up to the task, then show the results to a liver specialist (hepatologist) who is.
My PCP today said to treat it as UND - 'it's as good as it gets'. Even if there is a tiny tiny amount there, my hope is that it should be slammed by now (shot 6 today), and, if I'm really on to it, at least I may get them to taper at the end. I will certainly discuss it next time I see the Specialist at 10 weeks - he did say he didn't need to do another PCR at Week 12, so I guess he believes my body's got a handle on it thus far (budget budget :-( ..). I have a road to go yet regardless of PCR's and, at least, got this one done (thanks to you all), and it looks a lot better than I expected!!!
Zazza; Comeagain - I came into tx with the hope that my liver could have a rest at least, given I was told a 50/50 chance of UND; I did mono 14 years ago, and my body has never tried the peg IFN or riba, so maybe I'm reacting similar to tx naieve. I would love to have the opportunity of a team dedicated and within budget to do what it takes, and am prepared to look at going private at the end of tx if necessary - I really appreciate what you are saying and the lengths you have both gone to in reaching a sustained outcome; you have given me a yardstick by which I can demand from my team.
Trish - congrats on reaching week 24!!! - you GO Girl; thank you for your valuable comments.
Jmjm - Thanks for coming into the discussion; I was hoping you would :-). And thank you again Mremeet (I actually said that name out loud in my head last night and 'got it'!!! hehe)
ChildAngel and Brent - You both have your stresses and I'm humbled by your support. Thankyou too, Deb. And Lauri, if it wasn't me you were talking about, sorry for taking over the thread - if it was, thanks for starting it.
I'm off to do some exercise to make my bloods increase!!! Not in a danger zone yet (apparently), but no more checks now for 3 weeks. Love & Prayers to all. Thank you.
Kristina
As it is started and the input here is so extensive, so many heads thinking together.....
the 'no more VL checks' is an issue also. The Dr. saying that concerns me as well. I have heard of no tx's where once you reach UND (let alone his 'almost UND') where they say "well, we won't need to do any more VL test now" and let you go thru the entire tx. I mean....and not to worry on this as it's not so common....but some actually drop or even reach UND and than the virus reappears, VL actually goes up during tx and that is an urgency in deciding the next step....to extend, stop tx, etc. I realize it's handled in different ways where you are, but tx is tx, no matter what the location and some things I would think would be 'standard practice'. While low chance of that happening for you, IF it did even knowing how early it came back would be important for tx in the future and so on. Sorry if this isn't too clear, 2:30 am and at the falling asleep stage :)
Now aren't you glad we nagged you to get that 4wk. VL test and put all this thinking into the mix :) ? EVERYONE should get that 4 wk VL!
Back in the AM, and thanks to all replies, LL
HCV RNA : < 15 IU/ml
HCV RNA: 15 but less than 43.
You can get a borderline result like Zazza's which means it is detected at <15 but not quantifiable.
You are RVR which is good thing. Because if you werent then you really would need to consider extending.
Hope this helps
CS
The thing is that if you were detectable but below linear range it might very well be noted as "<15 IU/ml". As I said above, the only way to find out is to find out how they note UND with this particular test.
And, Kristina, I am actually very happy for your result since I remember you to be a non-responder to the old interferon. I think your result is good indeed considering this. I think Lady Lauri is right that you probably were UND by week 5 or 6. It is, of course, up to you to decide whether you want to try to get an extension or not, being you were so close to UND at week 4. Maybe 36 weeks would be something to consider?
Zazza
The taqmantest start as a qualitative test just determen if there is any virus left and in this case it most probebly was according to the doctors statement.
Then the next fase of the test is quantitative and since there is so little left this test can´t measure the exact nr, but that it is <then 15iuml,( but it can still bee 20 because that exact the test isn´t ) but the qualitaive test has determen that there was virus activ and as jmjm said either there is or their aint.( close dosen´t shot a rabbit ) So they have to quess the nr a good guess is something between 5 and 20.
Its a so cold borderline result.
I´m in a studie for relapsers geno 2 and 3 and when I´ve got that result week 4 borderline my nurse told me theres a reason why i relapsed the first time and this bordeline week 4 result was quite common among relapsers.
Both drofi and smaug got a simular result with a test that was sensitive down to <10iuml.
Take care Kristina your on your way to SVR if you play the cards right that at least what I think.
ca
I also said that this test cant measure the exact nr but that it is <15iuml ( could also be 20 because the test aint that precise ), so a good guess would be something between 5 and 20.
And as jmjm pointed out either you are UND or your not ( close dosn´t shot a rabbit )
and I meant called not cold borderline result
Im still a bit confused if we're talking about one or two different people here who are unsure of their test results -- but if it were me, I'd get hold of the lab results myself, and research it myself. Research would include: (1) call the lab (ask for a supervisor or lab director): (2) Speaking to your doctor direclty: (3) Speaking to another liver specialist if you don't feel your doc is familiar with the test reports which unfortunatly seem to happen from time to time.
Its difficult enough to come to the right decision on whether or not to extend, but if you don't start off with the correct data, it becomes somewhat mute.
HCV RNA (Taqman)
(Range 15 IU/ml - 69 million IU/ml)
Week 4: DETECTABLE. Virus concentration is 2900 IU/ml.
Week 12: BORDERLINE VALUE. Repeatable borderline value.
Week 15: UNDETECTABLE.
Note on each slip:
"With real time PCR for hepatitis C RNA the high sensitivity for qualitative PCR is combined with a large, quantifiable measuring range. In the same analysis it is determined whether there is an ongoing hepatitis C infection or not, and if there is, the virus load present expressed in International Units (IU/mL). Comparison of methods with earlier used bDNA technique shows good linearity but that Roche new technique gives 0.5 log units (3 times) higher readings in IU/mL."
Kristina, I advise you and everyone else to get paper copies of your test results. Ask Sfbaygirl, you can not really trust the doctors to interpret these results correctly. Although I think a doctor would rather call you UND when detectable, than detectable when UND.
First it gives a range of 15 to 69 million. Then it says that a *qualitative PCR is combined with a large cquantifiable measuring range). Then it mentions bDNA later on.
1) Exactly how many different tests/steps are used here? (Quests "Heptimax" for example uses two steps -- a real time PCR with a wide dyanmic range and a quantitative TMA with a sensitivity of 5 IU/ml)
2) Is 15 IU/ml the low end of the quantitative tests or the sensitivity of the qualtiative, assuming we have at least two different tests going on?
3) If the 15 IU/ml is the low end of a quantitative, then is there a qualtitative used with even a lower sensitivity? Because if not, then a result of "<15 IU/ml" would appear to be conclusively UND, at least for this particular test.
4) What values/explanations did they give you on your week 12 test, other than "Borderline". Not sure what that means without number and context.
I agree re getting hard copy and not relying just on what you med team tells you. One of the nurses would ask me what my Heptimax results meant and I cringe to think what she might have told a patient if say the doc was out that day :) For one particular test issue the only way I got a straight answer was to speak to the lab director directly because even customer service didn't have a clue. It's unfortunate test results can't be written in clear English, Swedish, or whatever language one speaks.
To clarify, the bDNA test mentioned, is the old kind of tests they used earlier. To my surprise and anguish I realized that my baseline viral load of 120'000 IU/ml was based on such a test from 2005. So not only was my baseline viral load 1 1/2 years old, according to the note on the Taqman test this would equal 370'000 IU/ml with the Taqman test, and thus every comparison during tx with my baseline viral load must have been inaccurate. Oh well, hopefully it is water under the bridge by now.
Anyway, to try and answer your questions about my test results:
1) Two steps are used, one qualitative and one quantitative. In your words, a real time PCR with a wide dynamic range and a quantitative TMA with a sensitivity of 15 IU/ml. The upper limit being 69 million IU/ml.
2) 15 IU/ml is the lower end of the quantitative test. The qualitative test can measure detectability lower than that.
3) According to the doctor at the laboratory whom I talked with, who is a researcher on hepatitis C as well, the qualitative test giving a borderline result might mean anything between 5 and 20 IU/ml. So apparently the qualitative goes down to 5 IU/ml then.
4) I was told I had virus detectable at week 12, but once it comes below the linear range, ie below 15 IU/ml in this case, it is not possible to determine an exact amount. I was recommended to extend beyond 48 weeks, no definite number however. It was my own choice to go the full 72.
Hope this answered your questions, Jim.
"3) According to the doctor at the laboratory whom I talked with, who is a researcher on hepatitis C as well, the TAQMAN test giving a borderline result might mean anything between 5 and 20 IU/ml. So apparently the qualitative goes down to 5 IU/ml then."
If we want to go even deeper into this, I think a borderline result is that you can see that there is a reaction to virus being found but not being able to determine how much virus there is. I don't actually think it is two separate tests, but rather two parts of the same analysis. For example, if it were different shades of colors which show the amount of virus present, you might see that there is a change in color which would indicate the presence of virus, but the difference between such low viral loads as 5 and 15 IU/ml is so small that it hardly affects the shade of color at all. Thus you can see the test sample is detectable but not the actual viral load present. At higher viral loads the shades of color vary more. This is how I understood it to be from a discussion of borderline results on the UK hepatitis forum last year. A doctor who has himself been treated successfully for hep C was participating in this discussion and explained it like this.
The question I was raising is whether or not the tests taken by the (one or two ?) other people in the thread is the exact same test combo, or perhaps they just took part of the test, such as the quant? Like I mentioned earlier, my lab has over a dozen different HCV tests and more than that if you count combinations and testing reflexes. And as you suggest, relying on what your medical team tells you orally is not always a good idea. You did the right thing by getting hold of the actual test results and then researching that further. Hopefully they will do the same.
BTW sounds like three tests were used in your case per answer "1"-- a PCR with wide dynamic range, a tma quantitative down to 15 IU/ml and a qual that went lower.
It's easy to see how these thing can be confusing -- there should be a law about lab people writing lab reports -- but you would think that a doctor who charges money to treat people for HCV would at least take as much time and trouble as folks like you and I have to find out exactly what the results mean.
Mike
I totally agree with you that there are so many test versions available that everybody needs to get their own paper copy and do their own research when getting these kind of difficult to understand test results.
It seems in Sweden they use the term borderline to imply that the virus is there but they cannot quantify it. If it is two parts of the same analysis this terminology does make some sense, even if it is hard to understand. Borderline being between UND and detectable with a quantifiable viral load.
Their qualitative TMA "HCV RNA QUAL TMA" gives you only one of two results. The report either says "Virus Detected" or "Virus Not Detected". So simple and clear that even a doctor or nurse can understand it. Their "Heptimax" test is also pretty clear once you understand that it's really two tests if the first shows you under 50 IU/ml. If I remember correctly, at least one of the LabCorp tests has also resulted in some confusion here.
I didn't know anyone was still using the branched DNA tests. For what it is worth, I would have been considered UND if my any of my PCR tests had come back under the detection limit of 50 IU/ml until I took the Quantasure a few months ago.
As if this water wasn't muddy enough!
In the meantime, I know I'm responding (phew) detectable or not, so I have a better chance than I thought, and if my bloodwork lets me, I'll certainly look to extend some or at least taper (and still push for another PCR if this one does turn out to be minutely detectable).
The fact that I got the PCR at all is due to the responses from everyone here... Blessings crew - may your voyages stay smooth to the destinations.
jmjm, sure you got this by now, but it's just Kristina's pcr we're questioning. I wanted to ask you pro's as I wasn't sure, for her.And I also think they should do more VL testing thru out tx also. (just my opinion, hint, hint)
Zazza, thanks to you too for all your input. I actually understand most of this, math being NOT my forte.
Thanks all, we've given Kristina a lot for her tx brain to think on :)
LL
OMIGOD! DUH! Can't believe those 3 letters didn't come to my mind either!!
Thanks, LL
I have exactly the same results as you at Week 4 (using PaqMan) and was told by my Nurse that I was considered RVR and PCR negative. In other words, the virus was undetectable to the lowest limit of that particular test and that I could be zero. They kept stressing that I was considered negative.
I also questioned getting the <2 test but was told that they don't do that here in NZ. To be honest I don't know if I'm being told the truth or fobbed off and I would be very interested to know how you get on with requesting the more sensitive test. I also asked about getting the test done o/seas but pretty much hit a brick wall.
Also, I want to extend treatment to 48 weeks because of my previous non-responder status but I will have to fight for it and pay for it again. Still no Pharmac funding for me as I don't have enough liver damage! I am Grade 2.
There is so little info out there about G3A non-responders that I have been looking at re-treatment options for G1 non-responders as a guideline. The other thing that complicates my situation is that I took a study drug and I think that is what caused the major drop in my viral load, so I am not feeling all that confident about the SOC therapy and I would really hate to waste all my hard work thus far only to relapse and find out later that if I had stayed on longer I would have beat it! I also feel that if I treat for 48 weeks then I will know I have done my absolute best.
Anyway, I would love to know what progress you make with these two issues. Congrats on your RVR and keep on fighting the good fight!!!
M.
When did you last do the combo?? Was it with pegasys/riba or pegintron/riba? And I'm wondering whether they did a 4 week PCR last time?
I was adamant about needing to know whether I was RVR at 4 weeks; if I wasn't responding at all I couldn't see the point in doing 24 weeks without a PCR. At the moment I'm just hoping my WBC, neuts etc will hold long enough to get me though, and am very much looking forward to my 8 week bloods :-).
I've added you as a 'friend' and will send you a note..... lovely that you posted and big congrats on your RVR - if you got that on a trial I would've expected SOC to be able to hold it, but I gather your nervousness if you were a non-responder last time (nb - there's a bit difference between being a 'non-responder' and a 'relapser' - if you got the 4 week RVR it shows that you are responding.... that's what my medic team were celebrating. A non-responder has the chance of 'not responding again', whereas a relapser may have a better chance on stronger meds. That's my understanding.
Talk soon epiphany - sounds like you're going strong - GO GIRL :-)!!!!!!!!
Last time round on the tx (pegasys/riba in early 2004) they didn't do a 4 week PCR, only at 12 weeks and it was qualitive not quantitive. At the end of treatment all they said to me was that I was a non-responder but as they never did a viral load test I have no idea what kind of response, if any, I had.
Sometimes I feel we are a little in the dark ages down here in NZ, esp when I read about how people are having their treatments tailored overseas esp in the States.
I really applaud your determination to get the system to play ball with the 4 week test. I got mine because of the study (as I mentioned, getting on a trial was the only way for me to get treatment here) but when I was trying to get one back in 2004 noone wanted to know it wasn't accepted protocol. Protocol, schmotocol!!
It feels like the battle happens on many levels down here in NZ - first you have to fight to get treatment, and then you have to fight to get the right tests, and then you have to fight the damn virus! Phew!
Thanks again for your welcome :))
