Window for hcv ab test and hcv rna test?

HCV. Nowadays with polymerase chain reaction technology it is making "window" periods a less discussed issue. In my practice if I suspected a recent infection (say days to weeks old)..this test would show virons in your blood. Once this virus hits your bloodstream it explodes exponentially. Some people are fortunate that their bodies contain the infection..most do not.

What is the possibility of having a positive HCV ab screen but a negative HCV RNA PCR test?

5-10% It is uncommon. I have had several cases. It means a false positive hcv antibody test and if the RNA test is negative, nothing further needs to be done as you do not have hepatitis c infection in that case. Read more...
10% Around 10% of patients with hcv + will have negative PCR viral load. This means either a false positive (confirmed with negative riba) or cleared previous infection. Read more...

Without more info. and only the data you submitted in your question, I would put it together the way you did: the first Advia hepC Ab test was a false positive. I presume other experts who arranged your follow-up testing have suggested the same interpretation. Stay well:) Read more...

I Had a blood test & everything negative except the hep c ab w/refl to hcv rna, qn, pcr signal to cutoff the result is <1.00 what does that mean?

This is a very. convoluted way of saying "this is a negative test." First the antibody that fights off hep C was checked. Because it may take up to 3 months for the antibody to show up, a second test, the HCV RNA, was checked automatically (i.e., reflexively or w/refl). The cut off value of <1.00 means that the virus itself could be NOT be detected either. Hope this helps! Dr. Anne. Read more...

May be. You ought to disclose these results to the blood bank so that they may make a determination on your eligibility to donate along with other health factors. I commend you for considering doing your civic duty. Read more...

What are HCV RNA tests?

Blood test. Hcv RNA is a blood test that quantifies how mich virus you have in your body; also called your "viral load". It is measured from a standard blood draw and reported as iu (international units) per milliliter (ml). Read more...

My HCV RNA test is negative, so then how often should I get rechecked?

May be no need. This is apparently an RNA PCR (polymerase chain reaction) test that determines virus particles, or viral load in the body. This can be negative, but if an immunoblot test was positive, it would mean that you had an infection with hepatitis c and it was cleared. If the immunoblot was negative, then you never had an infection, and if you had an immunoassay and it was positive, then it was wrong. Read more...

My HCV RNA quantitative test result said target not detected. Shouldi be worried?

That is good. that means that the hepatitis C virus is not detected in your blood, which is good! if it is detected, it means you have active hepatitis C virus replication in the blood. Read more...

What do you suggest if my HCV RNA quantitative test result is target not detected. What is the risk?

Need more info. All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, is this the first test you had or were you under treatment for HCV? If the latter, stay on treatment to complete the course. Read more...

Could you tell me why if my HCV RNA quantitative test result is target not detected, what is the risk?

Did you have hcv. It depends, if you had hcv and now do not have detectable rna it would mean that treatment was effective but may need follow-up. Target not detected means just that, not that the target is absent with certainty. Sort of like not-guilty vs. innocent. Read more...
