Description
Why It’s Done (Purpose):
1. Diagnose Acute Hepatitis D Infection:
o The anti-HDV IgM test is used to diagnose an acute or recent infection with Hepatitis D in individuals who are already infected with Hepatitis B.
o It helps to confirm that a person is experiencing an active Hepatitis D infection, which can complicate Hepatitis B and lead to more severe liver damage.
2. Identify Co-infection or Superinfection:
o Hepatitis D can either occur as a co-infection (when a person is simultaneously infected with both Hepatitis B and Hepatitis D) or as a superinfection (when someone with chronic Hepatitis B becomes infected with Hepatitis D). This test helps distinguish Hepatitis D from Hepatitis B alone and assess the severity of the infection.
3. Monitor Chronic Hepatitis B Patients:
o Individuals with chronic Hepatitis B who develop Hepatitis D infection may experience more severe liver disease, including cirrhosis and liver failure. The test can help assess the presence of Hepatitis D in these patients, guiding treatment and management decisions.
4. Assess Risk of Liver Damage:
o The presence of Hepatitis D (especially in combination with Hepatitis B) significantly increases the risk of liver cirrhosis, liver failure, and liver cancer. Early detection through this test allows for more aggressive management.
Preparation Guidelines:
• No special preparation is typically required for this test.
• Fasting is not necessary.
• A blood sample is drawn from a vein.
• Inform your healthcare provider about:
o Any recent symptoms such as jaundice, fatigue, abdominal pain, dark urine, or fever.
o Any previous history of Hepatitis B infection or chronic Hepatitis B.
o Any recent travel to areas where Hepatitis B and Hepatitis D are more common.
o If you have been diagnosed with Hepatitis B, as it is a prerequisite for contracting Hepatitis D.
