i have been tested for HCV antibodies ...and the result came reactive ...with a comment that the optical density is alomost a cutoff, and i should have another test to confirm or exclude the infection ..should i take HCV rna by pcr test ??? can you advice me please what should i do ?
I have a feeling your screening test was 'weakly' positive, meaning a signal to cutoff ratio of >1 and <3. If this is true, there is a good chance the result is a false +. Ask for a 'Riba' test which is VERY specific for Hcv antibody. If the Riba is neg, your initial screening test was indeed false + and you can stop worrying. If the riba is +, that means you are for sure antibody + but not necessarily virus +. Then you take the Pcr qualitative test, which will check for the virus. Patients who clear hep c virus usually keep the antibodies for a long time, maybe for life.
