Hepatitis B Virus Surface Antibody

CERNER / EPIC MNEMONIC: HBS AB
POE DESCRIPTION: HEPATITIS B SURFACE AG AB; HBS AG AB; HBS AB
CPT CODE: 86706
TEST INFORMATION: The test includes detection of antibody to Hepatitis B virus antigen.
DAYS PERFORMED:

Specimen accepted daily

TURNAROUND TIME:

8 hours

CONTAINER TYPE:

Red top Vacutainer® tube or SST TM tube

SPECIMEN REQUIREMENTS: Blood (serum)
REJECTION CRITERIA: Excessive hemolysis, gross contamination of specimen, chylous serum, improper storage of specimen, inappropriate specimen container, insufficient specimen volume.
MINIMUM VOLUME: 5 mL blood (1 mL serum)
HANDLING INSTRUCTIONS: Specimen should be transported as soon as possible. When transportation is delayed, refrigerate.
REFERENCE RANGE: No Hepatitis B surface antibody detected
LIMITATIONS OF TEST: In those individuals who have been vaccinated with any of the available HBV vaccines, this test could be useful to show response. However, a positive result in this test cannot guarantee adequate protection from HBV infection.
METHODOLOGY: Enzyme immunoassay (EIA)
ADDITIONAL INFORMATION: The presence of HBsAg antibody indicates previous Hepatitis B infection and acquired immunity to HBV. This test can also be used to evaluate possible immunity in individuals who are at increased risks to further exposure to the Hepatitis B virus (i.e. hemodialysis unit personnel, venipuncturists, etc.). Anti-HBs can usually be detected several weeks to several months after HBsAg is no longer found, and usually persists for many years to a lifetime after acute infection has resolved. In an acquired HBV infection, the presence of the antibody without the presence of the HBsAg may indicate immunity from reinfection.
