Anyone knows what is Hepatitis C AB is this test says This patient's sample tests reactive with a high s/co ratio: >/=8.00. Samples with high s/co ratios have been shown to repeat as positive using a different methodology 95% of the time or greater ( CDC MMWR no. RR -3 , 2003 ) Therefore , additional testing for verificatin of the result is not recommended. Can anyone make since of this?
The lab is confirming that HCV antibodies have been detected, and that additional testing is recommended. Since the signal to cut-off ratio is quite high, a doctor would most likely forego the RIBA test for antibody confirmation, and order a NAC test which tests directly for the presence of virus at this point. There are three likely candidates for additional testing: bDNA, PCR or TMA serum RNA tests. A positive result in any one of these tests will confirm the presence of active HCV RNA, at which point treatment options should be discussed.
