Hepatitis D Total Antibodies with Reflex to PCR (Sendout)

Test Information: This test detects total antibodies (IgG and IgM) to the hepatitis Delta agent.

Ordering Recommendation:

• Screening for hepatitis D virus (HDV) infection
• Diagnosing HDV infection in patients with documented acute or chronic HBV who are at risk for HDV infection
• Consider hepatitis B virus (HBV) IgM core antibody testing to determine whether HDV infection is a coinfection or a superinfection with hepatitis B virus.

Test Algorithm: If the anti-HDV screening result is positive, Hepatitis D Quantitative PCR (Sendout) [RHEPDP] will be performed at additional charge.
