Hepatitis B Core Antibody IgM Blood Test
Hep B Core Antibody IgM Blood Test (Labcorp)
This test looks for the presence of Hepatitis B Core (HBc) IgM Antibodies. Hep B is a viral liver infection that is spread through exposure to infected blood or bodily fluids. It is the most common cause of acute viral Hepatitis. Core antibodies are produced by the body's immune system in response to the inner core of the hepatitis B virus. IgM antibodies develop shortly after infection and fade away after a short period of time. The presence of HBc IgM antibodies typically indicates that a person has an acute or current infection. People with a chronic hepatitis B infection may begin to develop IgM antibodies if the virus becomes active. Results of this test are qualitative and provide a positive or negative result.
Anti-HBc, IgM is not typically ordered by itself. Because IgM antibodies are only detectable for a short period of time, a negative IgM result is not enough to determine that a person has not been exposed to Hep B. Other tests such as the Hep B Surface Antigen and Hepatitis B Surface Antibody. are often ordered at the same time. Together, these tests can help to determine if a person has hepatitis B, whether they have an acute or chronic infection, or if they have immunity due to vaccination or natural recovery. Request A Test offers a Hepatitis B Panel which includes all 3 tests at a discounted price.
This test is typically ordered when someone has symptoms of viral hepatitis including jaundice, fever, nausea, dark colored urine, loss of appetite, muscle aches, and stomach pain.
Turnaround for this test is typically 1-2 business days.

IgM core antibodies are typically detectable within a few weeks of infection and fade to undetectable levels after 4-6 months.
It is recommended that someone taking Biotin (also known as vitamin B7 or B8, vitamin H, or coenzyme R) stop consumption at least 72 hours prior to the collection of a sample.STD OVerview
