About the Test

The Hepatitis A, B, and C Profile is a comprehensive diagnostic panel designed to assess exposure, immunity, and active infection related to the hepatitis A, B, and C viruses. This profile includes several specific tests:

1. 1. Hepatitis A Immunity (IgG/IgM): This test checks for both recent (IgM) and past (IgG) exposure to the Hepatitis A virus (HAV), helping to determine if a person has developed immunity, either from a previous infection or vaccination.
2. 2. Hepatitis A IgM Antibodies: Specifically detects IgM antibodies to HAV, which are typically present in the early stages of an infection, indicating a recent exposure.
3. 3. Hepatitis B Surface Antigen (Hep B sAg): Detects the presence of the surface antigen, a protein on the surface of the Hepatitis B virus (HBV), indicating an active HBV infection.
4. 4. Hepatitis B Surface Antibodies (Immunity): Measures antibodies developed in response to a HBV infection or a vaccine, indicating immunity to Hepatitis B.
5. 5. Hepatitis B Core IgG/IgM: Tests for antibodies produced in response to a core protein of the HBV. IgM antibodies indicate a recent or acute infection, while IgG antibodies suggest past exposure or chronic infection.
6. 6. Hepatitis C Abs (Antibodies): Screens for antibodies to the Hepatitis C virus (HCV), indicating exposure to the virus. However, it doesn't differentiate between an active or past infection.
7. 7. Hepatitis C Antigen (Hep C Ag): Detects the presence of antigens from the HCV, indicating an active infection.
8. 8. Liver Function Tests (LFTs): This group of tests assesses liver function and includes measurements like ALT, AST, bilirubin, and albumin levels. LFTs are crucial for evaluating the impact of hepatitis on liver health.

This profile is vital in diagnosing and managing hepatitis infections. It helps in distinguishing between different types of hepatitis, determining the stage of infection, evaluating liver damage, and guiding treatment decisions.
