Specimens are screened for the presence of Hepatitis B surface antigen. Hepatitis B Surface Antigen is the first antigen to appear following an infection and can be detected serologically as an aid in the lab diagnosis of acute hepatitis infection. The performance of this assay has not been established with cord blood, neonatal specimens, cadaver specimens, heat-inactivated samples or body fluids other than serum.
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
Specimen may be stored at room temperature up to 8 hours; specimen should be frozen if assay will not be completed within 72 hours of collection.
