divergent pcr results pcr 6 months post tx
I just complete 6 months after tx (rib+peg interf), and did two PCR in two different labs:
1) First Lab:
test was taken 6 months post tx
result: 151 UI/ml
detection limit: 25UI/ml
2) Second lab:
test was taken 7 months post tx
result: undetected
detection limit: 15UI/ml
I am very confused. How can have two divergent results? Can we say that there was a false positive or false negative in PCR? Have someone experienced divergent results?
Is it is relapsed, viral load should not be higher after 6 months? Only 151UI/ml?
I have been undetected since 4 weeks, undetected at 12 and 24 weeks (geno 3). It was a 24 weeks of tx.
Sory for my english (second language).
Thanks in advance!

Congratulations on your SVR. What a horribly stressful thing to have happen to you. You must have been so scared and confused. I'm so glad that it ended well.

I repeated the tests in both laboratory and both gave UND, 31 weeks post tx :-) Very happy SVR! Thanks for your answer.

Given the fact you RVR'd (UND @Wk.4) and still UND at the end of tx.would lead me to believe the 6 mo.post tx.PCR was a lab error and this would seem to be backed up by the 7Mo. post UND. result.
Personally what I would do is have another PCR and if it is UND. then it would ascetain a certain SVR
Good luck and let us know...
