NEET PG Medical – 2020 – Question – 91

Correct Answer – A
Answer- A- Immunochromatography assays
HBV chronic carriers are those in whom HBsAg persists for more than 6 months in the presence of HBeAg or anti-HBe. HBsAg may persist for years after the loss of HBeAg. The most useful detection methods are enzyme-linked Immunosorbent assay for HBV antigens and antibodies and PCR for viral DNA -Jawetz 27/e pg- 504
Serological assays detect the host immune response (antibodies to HCV) or a viral antigen (HBsAg, HCVcAg). They are based on the immunoassay principle and are available in the form of rapid diagnostic tests (RDTs) or laboratory-based enzyme immunoassays (EIAs), chemiluminescence immunoassays (CLIAs) and electro-chemiluminescence immunoassays (ECLs).-
