Chlamydia PCR sample

[remorseful1]

Hi

Yesterday, I gave a urine sample to a lab for a Chlamydia PCR.  The sample has to be flown to another country to do the test (5-6 hour flight).  It was my first voiding that morning and I voided directly into the sample cup.  However, I'm worried that I gave too large a sample (nearly filled the cup, which, in my estimation was close to 100 mL).

Should I go back and give a new sample tomorrow? I really want it to be as accurate as possible and I read somewhere on this site that the sample should be no more than 30 mL.

Thanks.

she was diagnosed with yeast. that is the cause of most of her problems. it can cause ulcerations too when it's a humdinger.

yes, a swab is good for gonorrhea testing.

I'd be seen elsewhere and not even mention std's. no reason to think your symptoms are std related.  

have they screened you for kidney stones yet?

And about treatment: yes we've both taken the Zithro (I actually took 2.5g over three days), but I'm approaching 2 weeks with no let-up in symptoms.  If anything, they're getting worse, including lower ab/groin pain and pain in my right flank that lasted hours yesterday.  Something is definitely going on down there; either a super-resistant Chlamydia or something else but you have to understand that any doctor I go to in this country will immediately think "Chlamydia" hence the need for testing to be able to get to the bottom of things.

Thanks for your answer, grace.  Why doesn't it appear to be the case to you?

[gracefromHHP]

and yes I get the whole theory that perhaps you two are passing it back and forth but it really doesn't appear to be the case. it's unfortunate your urologist has been causing you this much unnecessary stress over all of this :(  

[gracefromHHP]

you and your wife have  already treated for chlamydia so continued testing at this point is pointless - make sense?  your last urine testing barely showed signs of infection as you were already told by HHH also.

also fyi - most clinics in the US don't use pcr to test for chlamydia either.  most are doing urine testing with naat testing, since most facilities don't have pcr capabilities.


that all said - to answer your question, it doesn't matter how much urine you gave as a specimen. the lab only uses the amount it needs to do the testing.

Vance, that is true, he did say that.  But he also said that the symptoms and test results are consistent with Chlamydia (which, in his opinion, would have to have occurred from a different incident). He also said I should follow the advice of my urologist, who did diagnose me with Chlamydia and prescribed Azithromycin (which both my wife and myself have taken). A positive PCR test will settle the question once and for all (false positives are apparently non-existent) and a negative PCR would be the strongest evidence yet that I don't have it (sensitivity is only about 80-85%).  So, with all due respect, I don't see anything unreasonable about wanting to do this test, which is the test I would have been given at the outset had I been living in the US anyway.

Now, if someone has a reasoned and informed answer to my question above, that would be greatly appreciated.  Thanks.

I didn't see where Dr.HHH said that, what I did hear him say is that you did not have a risk form the activity you described to him.

[remorseful1]

Dr HHH told me he could not rule out Chlamydia and that a DNA test was the only way to know for sure.

[gracefromHHP]

why are you still testing for chlamydia after what HHH told you on the std experts forum?
