Understanding Viral Marker Screening (HIV, HBsAg, Anti-HCV) in Kattupakkam
What is Viral Marker Screening (HIV, HBsAg, Anti-HCV) in Kattupakkam?
A Viral Marker Screening (HIV, HBsAg, Anti-HCV) test, also known as the Triple H test, helps screen for infections caused by three significant viruses: Human Immunodeficiency Virus (HIV), Hepatitis B Virus (HBV), and Hepatitis C Virus (HCV). This test detects the presence of viral markers, including antigens and antibodies, produced by the body in response to hepatitis B, hepatitis C, or HIV infections. Also, it helps determine the stage of infection, assess the immune response, and monitor treatment response. It is available at an affordable price in Kattupakkam with Tata 1mg Labs.
Your doctor may suggest a Triple H (HIV, HBV, HCV) test if you have risk factors for HIV, HBV, or HCV infections, including weakened immunity, unsafe sexual practices, intravenous drug use, occupational exposure to blood, or potential exposure through medical procedures. Additionally, a Triple H (HIV, HBV, HCV) test may also be done in pregnant women as a part of prenatal care, as these infections can be transmitted from a mother to her unborn child.
No special preparation is needed for this test. However, it is mandatory to fill out a consent form for HIV testing and undergo pre-test counseling (Annexure - CR/01) before sample collection.
What does Viral Marker Screening (HIV, HBsAg, Anti-HCV) measure?
Contains 3 testsA Viral Marker Screening (HIV, HBsAg, Anti-HCV) test includes screening of three transmissible viral infections, namely hepatitis B surface antigen, hepatitis C virus antibody, and HIV combo (antigen and antibody) test. These tests evaluate the presence or absence of the viruses causing hepatitis B or C and acquired immunodeficiency syndrome (AIDS) in your blood sample.
HIV Combo (antigen and antibody) test simultaneously detects HIV p24 antigen and antibodies associated with HIV 1 & 2. The HIV p24 antigen is the most abundant HIV protein and its detection is used clinically to diagnose an HIV infection early on since HIV-specific antibodies are not detectable in a very recently acquired infection. HIV-1 was discovered first and is the most widespread, whereas HIV-2 is more than 55% genetically different from HIV-1. The transmission rate of HIV-2 is also slower than HIV-1. This test also helps to differentiate between the two HIV infections.
Hepatitis B surface antigen test screens for the presence of hepatitis B virus (HBV) in an individual. HBsAg is the first serological marker, within 1 to 10 weeks, to appear in the blood after recent exposure to HBV. Persistence of this marker for more than 6 months implies chronic (long-term) HBV infection, which may lead to liver damage (scarring or cirrhosis). A person who has a chronic infection is capable of spreading the infection to healthy individuals, even if they do not show or experience any symptoms.
The hepatitis C virus antibody test determines if you have been infected by the hepatitis C virus (HCV) and helps your doctor guide your treatment. HCV causes liver inflammation and is classified into acute hepatitis infection and chronic hepatitis infection .This test is used for screening for anti-HCV antibodies.
- Acute hepatitis C: This occurs in the first six months after exposure to the hepatitis C virus. In the early stage of the infection, acute hepatitis C is mild and may cause no symptoms. For this reason, most people do not know they have this infection.
- Chronic hepatitis C: If your body is unable to fight off the virus, you can develop a chronic hepatitis C infection. Progression from acute to chronic hepatitis C is common, occurring in about 75-85% of patients. Detecting chronic hepatitis C at the early stage is important to prevent future complications, such as liver failure, and initiate effective treatment.
Hepatitis C Virus (HCV) Antibody
The Hepatitis C Virus (HCV) Antibody test determines the status of current hepatitis C virus (HCV) infection or past HCV infection that has been resolved. This test, therefore, helps your doctor to guide an appropriate treatment plan. HCV causes liver inflammation and is classified into acute hepatitis infection and chronic hepatitis infection.
- Acute hepatitis C: This occurs in the first six months after exposure to the hepatitis C virus. In the early stage of the infection, acute hepatitis C is mild and may cause no symptoms. For this reason, most people do not know they have this infection.
- Chronic hepatitis C: If your body is unable to fight off the virus, you can develop a chronic hepatitis C infection. Progression from acute to chronic hepatitis C is common, occurring in about 75-85% of patients. Detecting chronic hepatitis C at the early stage is important to prevent future complications, such as liver failure, and initiate effective treatment.
The Hepatitis C Virus (HCV) Antibody test is used for screening for anti-HCV antibodies. A reactive result needs to be confirmed by other more specific NAT/ nucleic acid tests before final diagnosis.

Hepatitis B Surface Antigen (HBsAg)
The Hepatitis B Surface Antigen (HBsAg) test detects the presence of a specific protein on the surface of the Hepatitis B virus (HBV) in the bloodstream. This protein, HBsAg, serves as a crucial marker for identifying HBV infection. This is a screening test and the diagnosis of any reactive HBsAg result relies on additional supplemental tests like anti-HBs antibody and total anti-HBc antibodies. Confirmation can be done using nucleic acid tests like HBV DNA by PCR. The Hepatitis B Surface Antigen (HBsAg) test is essential for identifying individuals who require medical intervention, such as antiviral therapy, and for implementing measures to prevent the spread of Hepatitis B virus to others.

HIV Combo (Antigen And Antibody) Test
An HIV Combo (Antigen And Antibody) Test simultaneously detects HIV p24 antigen and antibodies associated with HIV 1 & 2. The HIV p24 antigen is the most abundant HIV protein and its detection is used clinically to diagnose an HIV infection early on since HIV-specific antibodies are not detectable in a very recently acquired infection. HIV-1 was discovered first and is the most widespread, whereas HIV-2 is more than 55% genetically different from HIV-1. The transmission rate of HIV-2 is also slower than HIV-1.
