Determination of chronic hepatitis B status

 

This test is not suitable as stand-alone prenatal screening test of hepatitis B surface antigen status in pregnant women.

 

This test is not offered as a screening or confirmatory test for blood donor specimens.

 

This test is not useful during "window period" of acute hepatitis B (ie, after disappearance of hepatitis B surface antigen and prior to appearance of hepatitis B surface antibody).

If the hepatitis B surface antigen (HBsAg) result is reactive, then the HBsAg confirmation testing will be performed at an additional charge.
