Hepatitis A IgM Blood Test

Acute or Recent Exposure

Test Code: 006734
Specimen Type: Blood
Hepatitis A IgM Blood Test Online

Description:

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.

Detection Period:

Hepatitis A IgM antibodies are usually detectable 3 to 4 weeks after an initial exposure and return to normal after about 8 weeks. 

Requirements:

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.

Requirements:

Dietary supplements containing biotin (also known as vitamin B7 or B8, vitamin H, or coenzyme R) may interfere in assays and may skew results to be either falsely high or falsely low. For people receiving the recommended daily doses of biotin, draw samples at least 8 hours following the last biotin supplementation. For people on mega-doses of biotin supplements, draw samples at least 72 hours following the last biotin supplementation.
