Description
Hbc Igg
Sample Type: Serum
Tests Included:
Hepatitis B Core Antibody Immunoglobulin G (IgG) measurement
Sample Required:
Blood sample
Test Time:
Results typically available within a few days.
Test Range Values:
Interpretation based on presence or absence of IgG antibodies.
What is the test?
This test detects IgG antibodies against the core antigen of hepatitis B virus (HBV), indicating past infection or immunity.
Test Procedure:
A blood sample is collected and tested for the presence of IgG antibodies against HBV core antigen.
When to take the test:
When past HBV infection or immunity needs to be confirmed.
Who should take the test:
Individuals at risk of HBV exposure or those who require confirmation of immunity.
Precautions for exceptional cases:
Inform your healthcare provider about any ongoing illnesses or medications that might influence the test results.
Frequently Asked Questions (FAQs) for Hbc IgG:
Q1: Can Hbc IgG antibodies protect against future HBV infections?
A: While they indicate past exposure or immunity, their protective role against future infections might vary.
Q2: Can this test detect current HBV infection?
A: No, this test specifically identifies past exposure or immunity; other tests are used to diagnose current infection.
Q3: What does it mean if someone tests positive for Hbc IgG but negative for HBsAg (surface antigen)?
A: It could indicate past infection with resolution and the development of immunity without chronic HBV presence.
Q4: Can vaccination against Hepatitis B produce Hbc IgG antibodies?
A: No, vaccination typically triggers the production of surface antibodies (HBsAb) rather than core antibodies.
Q5: Can medications or health conditions interfere with the accuracy of this test?
A: Certain medications or immune-compromising conditions might affect antibody production, potentially impacting test results.
*Please note that specific testing protocols and guidelines may vary based on the latest recommendations from health authorities and regulatory agencies. It is essential to consult healthcare professionals and follow local testing guidelines for accurate and appropriate testing.
