Get rapid and accurate answers about new hepatitis B symptoms with Scan4Health’s Anti-HBC IgM Test—a specialized blood test for detecting Immunoglobulin M (IgM) antibodies against the hepatitis B core antigen. This assay is the gold standard for confirming an acute or recent hepatitis B virus (HBV) infection, supporting timely diagnosis, treatment, and public health management. Scan4Health provides fast reporting and expert interpretation to guide every step of your care.

• Routine Preparation: No fasting is required unless specified for additional labs.
• Symptoms/Exposure: Clearly inform your physician of new symptoms (jaundice, fatigue, abdominal pain, nausea, dark urine), risk factors, recent hepatitis exposures, or travel.
• Medication Guidance: List all current medications and recent vaccinations or immune therapies; do not stop treatment unless advised.
• Other Labs: The test is often performed alongside liver function tests (ALT, AST, bilirubin), HBsAg, and HBV DNA to provide a complete picture.
• Procedure Comfort: Wear a shirt with sleeves that can be easily rolled up for simple blood sampling.

This blood test detects IgM antibodies against the hepatitis B core antigen—an essential indicator of acute or recent hepatitis B infection (less than 6 months). These antibodies form rapidly after exposure to HBV, peak during the acute phase, and disappear within weeks to months. A positive Anti-HBc IgM result is diagnostic for a new or reactivating infection and helps distinguish fresh hepatitis B from chronic, past, or vaccinated states. Doctors recommend the test for individuals with new liver inflammation, unexplained jaundice, abnormal liver enzyme results, or when acute hepatitis B is suspected. Unlike total anti-HBc (which may remain positive for life), IgM antibodies specifically identify acute infection. A negative result, in the absence of symptoms, excludes recent hepatitis B, but chronic carriers may sometimes show short-term positivity during viral flares. The test does not detect immunity from vaccination.
