Hepatitis B Core (HBc) Immunostain, Technical Component Only
Use
The test is useful for aiding in the identification of hepatitis B infection, particularly in the chronic active state. The hepatitis B nucleocapsid contains 2 serologically distinct antigens, core and envelope antigens, surrounded by an outer envelope-hepatitis B virus surface antigen. The core antigen is more commonly present in chronic active hepatitis compared to the surface antigen, which is found in the carrier state.
Special Instructions
Not provided.
Limitations
This test does not provide pathologist interpretation, only the technical performance of the stain. Interpretation should be performed in the context of the patient's clinical history and other diagnostic tests by a qualified pathologist. The age of a cut paraffin section can affect immunoreactivity, and stability thresholds vary widely among published literature and are antigen dependent. The charge on glass slides can be affected by environmental factors, which may alter staining consistency.
