Overview
The primary purpose of the Anti-HBc IgM test is to diagnose acute Hepatitis B virus (HBV) infection. It identifies recent infections by detecting IgM antibodies, which are produced early in the infection. This test is essential for differentiating between acute and chronic HBV infection, especially when other markers like HBsAg are negative. It aids in guiding treatment decisions, monitoring infection status, and preventing further transmission.

Understanding Your Results
Positive
Indicates acute or recent Hepatitis B virus infection. Correlate with symptoms and other HBV tests.
Negative
No current infection detected, or infection occurred in the past with developed immunity. Consider testing for other markers if symptoms persist.
Equivocal
Repeat testing or perform additional confirmatory tests recommended.
If the test is positive, or if you experience symptoms like jaundice, fatigue, or abdominal pain, consult a healthcare provider immediately for further evaluation and management.
Limitations
- ⚠May not detect very early infections before antibody production
- ⚠False positives can occur in certain conditions like autoimmune diseases
- ⚠Should be interpreted alongside other HBV serological tests for confirmation
- ⚠Not suitable for screening chronic HBV carriers
