I am confused as to whether I am asking about specifcity or sensitivity...but in regards to accuracy (meaning not false pos or neg) is a PCR RNA Quan or Qual generally more consistent?
| Response from Dr. Dieterich
HCV PCR Qualitative is usually sensitive down to 50 copies while the Quant is to 600-1000 copies. Not really that important because unlike HIV HCV very rarely lives down at that low level. I always use the quant, no real reason to use the qual and there are more false positive with the qual. DTD
