What Does a Viral Marker Test Check?

Description

Viral infections such as HIV, hepatitis B and hepatitis C can affect the body for a long time without causing obvious symptoms. In some cases, a person may feel completely well while an infection is already present. This is one reason screening can be important, particularly for people who may have been exposed to these viruses or have certain risk factors.

Viral Marker Screening (HIV, HBsAg, Anti-HCV) is a blood test that checks for specific markers associated with three important viral infections: human immunodeficiency virus (HIV), hepatitis B virus (HBV) and hepatitis C virus (HCV). The markers tested are related to either the virus itself or the body’s immune response to infection. The viral marker test price may vary depending on the laboratory, testing method and location.

HIV affects the immune system, particularly CD4 cells, which play an important role in defending the body against infections. Without appropriate treatment, HIV can gradually weaken the immune system and may eventually lead to acquired immunodeficiency syndrome (AIDS).

Hepatitis B and hepatitis C primarily affect the liver. Hepatitis B is caused by HBV, while hepatitis C is caused by HCV. Some infections clear on their own, but others can become chronic. Long-term infection may cause liver inflammation and, in some people, lead to complications such as liver scarring, cirrhosis or liver cancer.
