Thank you very much for your answer. A final follow up would be great.
Since the pos Cryo I have had two neg HCV RNA Quant over a two month window and negative antibody with negative RIBA.
I have two final questions.
1.Has the Cryoglobulin been known in any way to prevent the other tests from showing positive?
2. Can the Cryo show a false positive?
Thanks very much
Response from Dr. Dieterich
The cryo's can cause a false positive antibody test and can also block the antibody test. However if the PCR is negative, then there is no virus and immunosuppressives would be the answer. I would suggest re doing the PCR however after starting the steroids just to be sure. DTD
