22736 Hepatitis Panel, Acute

Hepatitis Panel, Acute
Test Code: AS
Synonyms/Keywords
Panel, Hepatitis Acute​
Test Components
Hepatitis A Antibody IgM, Hepatitis B Surface Antigen, Hepatitis B Core Antibody IgM and Hepatitis C Antibody.
Useful For
In the diagnosis of acute viral hepatitis caused by the three most common viruses in the USA: hepatitis A, hepatitis B, & hepatitis C.
Specimen Requirements
Fasting Required Specimen Type Preferred Container/Tube Acceptable Container/Tube Specimen Volume Specimen Minimum Volume
(allows for 1 repeat)
Pediatric Minimum Volume
(no repeat)
No​Serum​Serum Separator Tube (SST)​Red Top Tube (RTT)​2 mL​1.5 mL​1 mL​
Collection Processing Instructions
Separate serum from the blood within 60 minutes of venipuncture and transport in an aliquot tube. Specimen must be free of particulate matter including fibrin. Specimens should be tested as soon as possible after collection and stored at 2 to 8°C if not tested immediately. The frozen specimens should be completely thawed thoroughly mixed and centrifuged before analysis.
 
High doses of exogenous biotin (also termed Vitamin B7, Vitamin H or Coenzyme R) may interfere with this assay (A-M, ABC-M, HAA). It is recommended that patients refrain from consuming any multivitamin or supplement containing biotin for at least 72 hours prior to collection of a blood sample.
Specimen Stability Information
Specimen Type Temperature Time
Serum​ ​ Refrigerate​ 2 days​
Frozen​ at -20 °C 6 months
​Frozen at -70 °C ​>6 months
Rejection Criteria

Interference
Heterophilic antibodies in human serum can react with the immunoglobulins included in the assay components causing interference with immunoassay.

Test Information

Acute hepatitis may be caused by viral infection, non-viral infection, or non-infectious causes. Hepatitis A is transmitted by the oral-fecal route, while hepatitis B & hepatitis C are primarily borne by blood and other body fluids. While all three viruses can cause acute viral hepatitis, only B & C can progress to a chronic infection.

Limitations:
• The results determined by different assays from different manufacturers can vary due to differences in assay specificities and cannot be used interchangeably.
• For other limitations consult individual test reference assay entries.

Reference Range Information
Performing Location Reference Range
Marshfield​ Tests reported as "Reactive" or "Non-reactive"​
Interpretation

Results may be interpreted as follows: 

  • Reactive hepatitis A IgM antibody is indicative of acute infection. 
  • Reactive hepatitis B surface antigen and reactive hepatitis B core IgM antibody results indicates acute hepatitis B infection. 
  • Reactive hepatitis B surface antigen and non-reactive hepatitis B core IgM antibody is indicative of chronic hepatitis B. 
  • Reactive hepatitis C antibody indicates either acute or chronic hepatitis C infection. The Hepatitis C Virus RNA, Quantitative test (test code HCVQT) may be used to detect ongoing viral replication.
