Diagnosis of acute, recent, or chronic hepatitis B infection
Determination of chronic hepatitis B infection status
This test is not offered as a screening or confirmatory test for blood donor specimens.
This test, by itself , is not useful during the "window period" of acute hepatitis B virus (HBV) infection (ie, after disappearance of hepatitis B surface antigen and prior to appearance of hepatitis B surface antibody ). Testing for acute HBV infection should also include hepatitis B core IgM antibody (anti-HBc IgM).
Test ID | Reporting Name | Available Separately | Always Performed |
---|---|---|---|
HBGNT | HBs Antigen Confirmation, S | No | No |
If hepatitis B surface antigen (HBsAg) screen is reactive with signal-to-cutoff (S/CO) ratio in the range of 1.00 to 100.0 then HBsAg confirmation will be performed at an additional charge.
