I'm new here, and while I understand almost all of the acronyms and abbreviations - I can't figure out what SVR is. Somebody? Thanks!!

Btw, I did not say that plain SVR does NOT mean 6 months post tx, but said that it does not ONLY refer to that, but also is referred to in the other terms mentioned.

[Marcia2202]

That's exactly what I was referring to, clinical trial data and doctors papers and presentations. I've been reading these expressions on a lot of literature on CCO.

No, the generally accepted medical definition for SVR is undetectable after 6 months."

Generally - if you are UND at 4 weeks post it means your chance of SVR are like 99.9%

So, basically I'd take that as being SVR at that point.  It's just our peace of mind that we need. that.1% is just really like saying birth control is 99% effective - everybody needs a disclaimer.

as far as I know, SVR still means UND six months post treatment. SVR 4, 12 and such, are simply adjuct terms often used when presenting clinical trial data although SVR 12 ( 12 weeks posttreatment) is starting to become accepted as equivocal to SVR 24, commonly referred to as simply SVR. SVR is also the same as "cure" and is durable close to 99%. After one year, it's durable close to 100%.

No, the generally accepted medical definition for SVR is undetectable after 6 months.  

The other acronyms you mention simply indicate undetectable levels at various points in time after treatment.

Thanks I didn't know that--now I do.

[Marcia2202]

A little correction.... here on the forum it is mostly used as 6 months post tx undetected, but in medical language SVR can be referred to any time of sustained virological response after finishing treatment and is usually expressed i.e. as SVR4 , SVR12, SVR24 meaning SVR at weeks post tx etc.

[Tippyclubb]

Sustained Virological Response which means the virus is undetected 6 months after treatment ends.  If you look to the right of this forum and scroll down you will see common Hep C acronyms, click on that and all the abbreviations are there.

Welcome to the forum.  Great people here.
