HBsAg Neutralization
| Also Known as (Alias) | Hepatitis B Surface Antigen Neutralization HBsAg Confirmatory |
| Indications | Confirmatory testing of samples found to be repeatedly reactive by the Abbott Alinity S HBsAg assay. |
| Method | Abbott Alinity S HBsAg Confirmatory assay |
| Test Information | Assay is a qualitative chemiluminescent immunoassay used to confirm the presence of HBsAg in human serum and plasma by means of specific antibody neutralization. |
| Sample Requirements | Living Donor: Serum or Plasma (EDTA, Potassium oxalate, Sodium citrate, ACD-A, ACD-B, CPD, CP2D, CPDA-1). Heparin anticoagulants are not acceptable. Cadaveric Donor: Serum |
| Requested Volume | 6 mL |
| Minimum Volume or Pediatric volume | 2 mL |
| Sample Information | For cadaveric donors, serum can be stored up to 2 days, after which serum should be removed from cells. |
| Shipping Information | Samples are acceptable at 2-8°C for up to 14 days; samples can be frozen at -20 °C or lower. |
