Viral Markers are laboratory tests used to detect specific antibodies, antigens, or viral RNA in blood, helping diagnose viral infections like HIV, Hepatitis B, Hepatitis C.
Indications for Viral Marker Testing:
● Hepatitis B and C: To identify infection with hepatitis viruses and to assess the risk of liver damage or chronic infection.
● HIV: To screen for HIV infection and to monitor viral load in patients on antiretroviral therapy.
● Before any routine surgery, viral markers are advisable to be done as a part of Pre Anaesthesia Checkup.
How Viral Marker Testing Works:
● A blood sample is collected and tested for the presence of viral antigens (proteins), antibodies (immune system markers), or viral RNA/DNA (genetic material).
● Techniques like enzyme-linked immunosorbent assay (ELISA), western blot, or polymerase chain reaction (PCR) are used to detect specific viral markers.
Normal Range:
● Negative result: No evidence of current or past infection with the tested virus.
Abnormal Test Significance:
● Positive result: Indicates current infection or past exposure to the virus. The test can also help determine whether the infection is acute, chronic, or if there is a risk of transmission.
Price in India:
Approx. ₹1,500 – ₹5,000 for viral marker testing.
