Testing & Diagnosis
Patients with HBV should be screened according to guideline recommendations
Not actual patients.
Test first for HDV antibodies,
then test for HDV RNA to diagnose active HDV infection1
The presence of anti-HDV is evidence of a past or ongoing HDV infection2
In a study, anti-HDV titers declined over time in resolved HBV/HDV infections2
For patients testing negative but have ongoing risk factors, consider periodic retesting for HDV antibodies1
Recommended tests for HDV*:
- Total anti-HDV (CPT code: 86692) Hallmark of prior or current infection
- HDV RNA PCR (CPT code: 87798, 87799) Marker of active infection and useful for monitoring therapy

AASLD recommends screening HBV patients with the
following risk factors1:
Persons born in regions with reported high hepatitis delta virus (HDV) endemicity
Persons with multiple sexual partners or any history of sexually transmitted disease
Men who have sex with men
Persons who have ever injected drugs
Persons with high ALT or AST with low or undetectable HBV DNA
Persons infected with the hepatitis C virus or HIV
Map of endemic areas5
The largest populations affected by HDV infection are
in Asia and Africa5
Persons from endemic regions account for about 52% of hepatitis
delta cases in the US6
