Acute Viral Hepatitis Diagnostic with Reflexes (HAV, HBV, HCV)

Test Code

AHPC or 10306

Alias/See Also

Acute Hepatitis Panel with Reflex

CPT Codes
80074

Includes

Includes:
Hepatitis A IgM Antibody
Hepatitis B Surface Antigen with Reflex to Confirmation
Hepatitis B Core Antibody (IgM)
Hepatitis C Antibody with Reflex to HCV RNA, Quantitative Real time PCR.

If Hepatitis B Surface Antigen is positive, samples will be confirmed based on the manufacturer's FDA approved recomendations at an additional charge (CPT code: 87341)
If HCV antibody is reactive, then HCV RNA Quantitative Real-Time PCR will be performed at an additional charge (CPT code(s): 87522)

Preferred Specimen

5.0 mL serum

Minimum Volume

2.5 mL

Instructions

Dietary supplements containing biotin may interfere in assays and may skew analyte results to be either falsely high or falsely low. For patients receiving the recommended daily doses of biotin, draw samples at least 8 hours following the last biotin supplementation. For patients on mega-doses of biotin supplements, draw samples at least 72 hours following the last biotin supplementation.

Clinical Significance

This panel is preferred to evaluate symptomatic patients for viral hepatitis and includes testing for hepatitis A virus (HAV), hepatitis B virus (HBV), and hepatitis C virus (HCV); the 3 most common pathogens of viral hepatitis in the United States [1].

Acute symptoms and signs are similar among HAV, HBV, and HCV infection and may include fever, fatigue, loss of appetite, nausea, abdominal discomfort, dark urine, pale stools, and jaundice [1]. This panel includes 4 tests with reflexes that may help establish diagnosis of these 3 viral hepatitis infections in symptomatic patients: HAV IgM antibody; Hepatitis B Surface Antigen (HBsAg) with reflex confirmation; Hepatitis B Core, IgM; Hepatitis C Virus antibody with reflex to HCV RNA. If acute HCV infection is suspected, the recommended test is Hepatitis C Antibody with reflex to HCV, RNA, Quantitative, Real-Time PCR.

If acute HBV infection is suspected, the recommended test is Hepatitis B Surface Antigen (HBsAg) with Reflex Confirmation. This panel is not intended for asymptomatic screening for viral hepatitis. The results of the test in the panel should be interpreted in the context of pertinent clinical history and examination findings.
