Description
Hbc Igm
Sample Type: Serum
Tests Included:
Hepatitis B Core Antibody Immunoglobulin M (IgM) measurement
Sample Required:
Blood sample
Test Time:
Results typically available within a few days.
Test Range Values:
Interpretation based on the presence or absence of IgM antibodies.
What is the test?
This test detects IgM antibodies against the core antigen of hepatitis B virus (HBV), indicating recent or acute infection.
Test Procedure:
A blood sample is collected and analyzed for the presence of IgM antibodies specific to HBV core antigen.
When to take the test:
When acute HBV infection is suspected or in cases where recent exposure to HBV is possible.
Who should take the test:
Individuals exhibiting symptoms of acute hepatitis or those at risk of recent HBV exposure.
Precautions for exceptional cases:
Inform your healthcare provider about any ongoing illnesses or medications that might affect the test’s accuracy.
Frequently Asked Questions (FAQs) for Hbc IgM:
Q1: Can Hbc IgM antibodies indicate chronic HBV infection?
A: Generally, IgM antibodies suggest recent infection rather than chronic HBV; however, interpretation may vary.
Q2: How long do Hbc IgM antibodies persist after acute infection?
A: IgM antibodies usually decrease within a few months post-infection but can persist for up to a year.
Q3: Can a person be infectious if they test positive for Hbc IgM?
A: Yes, presence of IgM antibodies may suggest active viral replication, making the individual potentially infectious.
Q4: Can vaccination for Hepatitis B produce Hbc IgM antibodies?
A: No, vaccination typically stimulates the production of different antibodies (such as surface antibodies – HBsAb) rather than core-specific IgM antibodies.
Q5: Can the presence of Hbc IgM antibodies guarantee symptoms of acute infection?
A: While IgM antibodies often accompany acute infection, some individuals might not exhibit noticeable symptoms.
