Description

The Quantitative detection Hepatitis B virus Surface IgG antibody (HBSAb) in human sera using the FDA approved Abbott ARCHITECT AUSAB-DIL test two-step chemiluminescent immunoassay.

In the first step, sample, assay diluent, and recombinant Hepatitis B surface Antigen (rHBsAg) coated paramagnetic microparticles are combined. Anti-HBs present in the sample binds to the rHBsAg coated microparticles. In the second step, rHBsAg acridinium-labeled conjugate is added, which binds to IgG anti-HBs. Then pre-trigger and trigger solutions are added to the reaction mixture. The resulting chemiluminescent reaction is measured as relative light units (RLUs).

A direct relationship exists between the amount of anti-HBs in the sample and the RLUs. The concentration of anti-HBs in the sample is determined using an active ARCHITECT AUSAB calibration curve. Results are reported as mIU/mL.

Processing

Processing

Blood: Specimens may be stored on or off the clot, red blood cells, or separator gel for up to 3 days at room temperature (15-30°C) or up to 7 days at 2-8°C. If testing will be delayed more than 3 days for specimens stored at room temperature or more than 7 days for specimens stored at 2-8°C, remove serum from the clot, red blood cells, or separator gel and store at -20°C or colder. Avoid more than three freeze/thaw cycles.

Outside Laboratories: Specimens may be stored on or off the clot, red blood cells, or separator gel for up to 3 days at room temperature (15-30°C) or up to 7 days at 2-8°C. If testing will be delayed more than 3 days for specimens stored at room temperature or more than 7 days for specimens stored at 2-8°C, remove serum from the clot, red blood cells, or separator gel and store at -20°C or colder. Avoid more than three freeze/thaw cycles.

Unacceptable samples: Cord blood, neonatal specimens, cadaver specimens, heat-inactivated specimens, or body fluids such as saliva, urine, amniotic fluid, or pleural fluid. Specimens with obvious microbial contamination or are grossly hemolyzed.
