How Can you know by lab tests that the patient has hepatites C?

An HCV antibody test is used to screen for infection. It detect the presence of antibodies to the virus indicating exposure to HCV. This test cannot distinguish between someone with an active or previous HCV infection.The following test may be used to diagnose the current infection and monitor treatment. HCV RNA test, HCV Viral load,

1.Detection of Anti  HCV( antiodies) in serum

 

2.HCV antigen quantification by RNA-PCR

By  HCV  Ab   Test

-detection of anti HCV antibodies in serum 

-performing PCR HCV antigen quantification

If an HCV infection is suspected. a serum antibody test is performed if the test is positive, a search of L RNA HCV by RT-PCR (reverse transcriptase reaction and amplification in polymerase chain reaction) can be performed to provide information on viremia..

Rapid Ab testing ELISA PCR

HEPA C ANTIBODY ...Becuse THE HEPA C NO VACCINATION ....

RT-PCR is prefer,however rarely False positive will be occurring in Elisa ab detection or  false negative in  lateral flow Rapid screen. complementary test can be western blot ag detection
