Rejection criteria

LABELING ISSUE (UNLABELED/ MISLABELED); MISSING REQUEST FORM; MISMATCH BETWEEN REQUEST FORM & SAMPLE DETAILS; MISSING AGE/ GENDER; WRONG SAMPLE TYPE; INSUFFICIENT SAMPLE; HEMOLYZED, LIPEMIC, ICTERIC SAMPLES.

Other Instructions

CENTRIFUGE SST (SERUM GEL TUBES) WITHIN 1-2 HOURS OF COLLECTION. CENTRIFUGE RED TOP VACUTAINERS AND ALIQUOT SERUM WITHIN 1-2 HOURS OF COLLECTION. THE SEPARATION VIAL MUST BE LABELED WITH AT LEAST 2 PATIENT IDENTIFIERS AND THE SAMPLE TYPE.

Reference intervals

NEGATIVE.

Clinical Utility

SCREENING FOR HEPATITIS C VIRUS (HCV) INFECTION. A PERSISTENTLY POSITIVE RESULT SHOULD BE FOLLOWED UP BY HCV PCR TESTING.

Test Limitations/ Confounders

ANTI-HCV USUALLY REMAINS POSITIVE FOR LIFE THEREFORE POSITIVITY DOES NOT DISTINGUISH BETWEEN RECENT VS. CHRONIC VS. RESOLVED INFECTION. FOR THIS DISTINCTION, HCV RNA/ NUCLEIC ACID TESTING IS REQUIRED AS A FOLLOW UP TEST. FALSE POSITIVE ANTI-HCV RESULTS CAN ALSO OCCUR.
