You conduct nucleic acid amplification testing (NAT) for which type of viruses?

Nucleic acid amplification testing (NAT) is a highly sensitive method used to detect the genetic material of viruses. This technique is particularly valuable in transfusion medicine and infectious disease diagnostics because it allows for the early detection of viral infections before the appearance of antibodies and antigen tests.

The correct answer includes HIV, HCV, and WNV as they are the primary viruses for which NAT is routinely performed.

HIV (Human Immunodeficiency Virus) is monitored through NAT to ensure that blood products are safe for transfusion, as this virus can lead to serious immune system complications. HCV (Hepatitis C Virus) is another important target for NAT because it can cause chronic liver disease and is transmitted through blood. The detection of HCV through NAT helps identify infected individuals during the "window period" when traditional serological tests may not yet be positive. Furthermore, WNV (West Nile Virus) is particularly relevant in blood donation settings during periods of endemic transmission seasons. NAT allows for the detection of WNV in blood donations, reducing the risk of transfusion-transmitted infections.

While HBV (Hepatitis B Virus) and HTLV (Human T-lymphotropic virus) are important viruses in their own right, NAT is
