Hepatitis A IgM Blood Test
Test Code: 006734
Specimen Type: Blood
Hepatitis A IgM Blood Test (Labcorp)
This test is used to screen for recent exposure to the Hepatitis A virus. Hep A is a liver infection which is typically spread through exposure to contaminated fecal matter. Some of the common ways Hep A is spread include
- Through contaminated drinking water
- Eating food prepared by someone who has not properly washed their hands
- Eating produce that has not been properly washed
- Eating seafood raised in contaminated water
- Through some forms of sexual contact
- Exposure to infected blood
This test looks for antibodies which develop shortly after infection. IgM antibodies are usually detectable 3-4 weeks after exposure and fade out after a couple of months. After recovery, IgG antibodies develop and often provide immunity from future infections.
Hepatitis A is typically associated with flu-like symptoms. Common symptoms include nausea, vomiting, diarrhea, abdominal pain, loss of appetite, fever, fatigue, and joint pain. In some cases, especially in younger children, Hep A may show no symptoms.
The Hepatitis A IgM Abs test is typically ordered by people who are experiencing symptoms associated with Hep A or have reason to believe they may have been recently exposed to Hep A. People wishing to test for past exposure to Hep A or to verify the status of their immunity to Hep A may wish to order the Hepatitis A Total test.
Turnaround time for the Hepatitis A IgM Abs test is typically 1 business day.

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
Hepatitis A IgM antibodies are usually detectable 3 to 4 weeks after an initial exposure and return to normal after about 8 weeks.
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.
