Hepatitis B Surface Antibody EIA
Hepatitis B Surface Anitbody EIA
Specimen Collection Instructions
Blood should be collected in a plastic, sterile STD Program approved collection tube. Please follow the manufacturer's instructions on clot time and centrifuge speed/time requirements.
The Virology Lab 96 form must be filled out completely. The following information must be included on the form:
Storage and Transport Instructions
Speciments should be shipped refrigerated (2-8ºC) within 7 days of collection. For longer storage, specimens must be frozen at -20ºC or colder. Frozen specimens must be shipped on dry ice and received at a temperature of -20ºC or colder.
Causes for Rejection
Limitations for the Procedure
For diagnostic purposes, results should be used in conjunction with patient history and other hepatitis markers for diagnosis of acute and chronic infection. A non-reactive test result does not exclude the possibility of exposure to hepatitis B virus. Results obtained with the MONOLISA™ Anti-HBs EIA assay may not be used interchangeably with values obtained with different manufacturers' anti-HBs assay methods. Results from immuosuppressed patients should be interpreted with caution. This assay does not differentiate between a vaccine-induced immune response and an immune response induced by infection with HBV. To determine if the anti-HBs response is due to vaccine or HBV infection, a total anti-HBc assay may be performed. Performance characteristics have not been established for therapeutic monitoring. A reactive anti-HBs result does not exclude co-infection by another hepatitis virus. Individuals that have received blood component therapy (e.g., whole blood, plasma, immune globulin administration) during the previous 3 to 6 months may have a false reactive anti-HBs result due to passive transfer of anti-HBs. The performance of the MONOLISA™ ANti-HBs EIA has not been establised with cord blood, neonatal specimens, cadaver specimens, heat-inactivated specimens, or body fluids other than serum or plasma, such as saliva, urine, amniotic, or pleural fluids.
