Description
Blood, Presence of HBcAg (core Antigen) in the cytoplasm and nucleus may reflect disease activity and predict response to antiviral treatment. Anti HBc IgM appears shortly after HBV infection and can be detected in serum soon after the appearance of circulating HBsAg and HBeAg. The levels are high during acute infection and typically disappear within 6 months, though it can persist in some cases of chronic hepatitis. Anti-HBc (IgG antibody) usually remains detectable for a lifetime. The Hepatitis B Core antigen test is used to detect hepatitis B virus (HBV) infection in an individual. This test also helps to assess the risk of re-infection/reactivation. Anti-HBc is the only serological marker that can detect HBV infection and potentially infectious blood. This test cannot differentiate between acute, chronic, and resolved HBV infection., Non Fasting
Sample Required:
The HBcAg IgM antibody test requires a blood sample, which is obtained by drawing blood from a vein in your arm.
Test Time:
The test results are typically available within a few hours to a few days, depending on the laboratory.
Test Normal Range:
The normal range for the HBcAg IgM antibody test is usually negative or non-reactive.
What is the test?
The HBcAg IgM antibody test is used to detect the presence of IgM antibodies against the hepatitis B core antigen (HBcAg) in the blood. It helps diagnose acute or recent hepatitis B virus (HBV) infection.
Test Procedure:
During the test, a blood sample is collected and analyzed in the laboratory. The presence of HBcAg IgM antibodies is determined using specific immunoassay techniques.
When to take the test?
The HBcAg IgM antibody test is typically performed when there is suspicion of acute or recent HBV infection. It is often ordered alongside other hepatitis B tests to confirm the diagnosis and assess the stage of infection.
Who should take this test?
Individuals who exhibit symptoms of acute hepatitis, such as fatigue, loss of appetite, jaundice (yellowing of the skin and eyes), dark urine, and abdominal pain, may be recommended to take the HBcAg IgM antibody test. It is also useful for those who have had recent exposure to HBV, such as through unprotected sexual contact or needle sharing.
Precautions for exceptional cases (pregnancy etc.):
If you are pregnant or have any other medical conditions, it is important to inform your healthcare provider before undergoing the HBcAg IgM antibody test. They will provide specific instructions or precautions based on your individual situation.
