| name | Hepatitis B virus surface Ab [Presence] in Serum, Plasma or Blood by Rapid immunoassay | ||
| description | Hepatitis B surface Ab (HBsAb) rapid tests are available in test strip and cassette formats from manufacturers in various countries including the US, Singapore, and China. (As of 8/25/2014, no HBsAb rapid test kits are approved for use in the United States). Hepatitis B surface Ab (HBsAb) rapid tests are used to test human blood for the presence of HBsAb. HBsAb appears in the blood shortly after the disappearance of HBsAg. This term was created for but not limited in use to, the iCare One Step HBsAb test kit which uses the sandwich principle, a solid phase colloidal gold enhanced immunoassay, to detect HBsAb in whole blood, serum, or plasma. Testing can be performed in approximately 20 minutes. | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | Hepatitis B virus surface Ab B = Buccal | ||
| property | PrThr = Present or threshold: The Property PrThr stands for “Presence or Threshold”, meaning either a) the actual presence or absence of an analyte, or b) that the amount of analyte detected is over some predetermined threshold. | ||
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | ||
| system | Ser/Plas/Bld Ser = Serum Plas = Plasma Bld = Whole blood | ||
| scale | Ord = Ordinal: Ordered categorical responses, e.g., 1+, 2+, 3+; positive, negative; reactive, indeterminate, nonreactive. | ||
| method | IA.rapid | ||
Additional Names | |||
| short name | HBV surface Ab SerPlBld Ql IA.rapid | ||

| change reason | The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.; The EIA method, which was always intended to cover more than just enzyme-linked immunoassay and whose display name for the long common name has always been Immunoassay, was renamed IA in order to eliminate ambiguity about whether the method has a broader meaning than just enzyme-linked immunoassay. Likewise, EIA.rapid was renamed IA.rapid. These changes were approved by the Laboratory LOINC Committee in June 2016. | ||
