Description
Why It’s Done:
The Hepatitis B Core IgM test is typically performed to:
• Diagnose an acute Hepatitis B infection: It is used when a person is suspected of having a recent Hepatitis B infection, especially if they present symptoms such as jaundice, fatigue, abdominal pain, or nausea.
• Identify recent exposure to the Hepatitis B virus: If someone has had contact with an infected person or high-risk activities (e.g., unprotected sex, sharing needles), this test helps confirm whether they are currently infected.
• Differentiate between acute and chronic Hepatitis B: The IgM antibodies are only present during the early stages of infection, helping to distinguish between acute infection and past exposure or chronic infection.
Preparation:
Preparation for the Hepatitis B Core IgM test is minimal:
1. Fasting:
o Fasting is not required for this test.
2. Medications:
o Inform your healthcare provider of any medications you are taking, especially those that may affect liver function or immune system activity.
3. Hydration:
o Be sure to drink plenty of water before the test to ensure easy blood collection.
4. Procedure:
o A blood sample will be drawn, typically from a vein in your arm.
5. Timing:
o This test is done as part of a workup for suspected acute Hepatitis B infection, so it can be performed at any time when infection is suspected
