Hepatitis B Core (anti-HBc), IgM antibody near me in Chandigarh

The hepatitis B (Core) IgM antibody, or anti-HBc IgM, is a specific type of antibody produced by the immune system during the active stage of a hepatitis B virus (HBV) infection. The immune system makes IgM antibodies for the core of HBV several weeks after an individual is infected. These antibodies are typically detectable in the blood during the early stages of acute infection, and their presence indicates that the infection is ongoing. 

It is noteworthy that individuals who have received the hepatitis B vaccine will not have the core antibody (anti-HBc) in their blood because the vaccine doesn’t provide protection in that way.  The detection of anti-HBc IgM is therefore a key marker for distinguishing an acute infection from a past or resolved infection, helping doctors assess whether the infection is recent or chronic. In some cases, it can also help identify individuals who may be in the "window period" of infection, when the hepatitis B surface antigen (HBsAg) may not be detectable but the HBV is still present in the body. Therefore, the test can help assess the timing and activity of the infection, which is crucial for treatment decisions.

The Hepatitis B Core (anti-HBc), IgM antibody is usually recommended to individuals who are showing symptoms of hepatitis B, such as nausea, loss of appetite, muscle aches, fever, jaundice (yellow skin and eyes), dark-colored urine, belly pain, etc. It is also advised for those at higher risk of exposure to the virus, including individuals who have had unprotected sex with someone infected with hepatitis B, live in close contact with an infected person, were born to a mother with the hepatitis B virus (HBV), or work in healthcare settings with potential blood exposure. 

A positive result may indicate that the infection is in its early, active phase and that the individual is potentially contagious. In contrast, a negative result can rule out acute infection and point towards other causes of symptoms or liver dysfunction. In conjunction with other tests, such as the Hepatitis B surface antigen (HBsAg) test and Hepatitis B DNA (viral load) test, the Hepatitis B Core (anti-HBc), IgM antibody test provides a comprehensive picture of an individual's hepatitis B infection status.

No special preparation is needed for this test. Eating and drinking can be done as per the daily routine. However, inform the doctor about all the medications or supplements or underlying liver conditions, as these factors may influence the test results. 

Lab test results may vary across laboratories. Talk to the doctor about the specific test results. Abnormal test results require an expert interpretation. Therefore, never try to self-medicate based solely on these results. Always consult a doctor for a proper understanding of the test results.
