LOINC Code
| LOINC code | 47361-1 | ||
|---|---|---|---|
| name | Treponema pallidum IgG Ab [Presence] in Serum from Donor by Immunoassay | ||
| description | This test is intended to be used as a primary screening test for the diagnosis of infection with Treponema pallidum, the causative agent for Syphilis. This test has been approved by the FDA for the screening of donors of human cells, tissues, and tissue-based products. A Positive Syphilis antibody test result is indicative of an acute or chronic infection with T. pallidum, and may be used to disqualify a potential cell or tissue donor. This test is not intended to be used for routine clinical diagnostic testing. False Positive results are known to occur, especially for patients with Lyme disease. | ||

Fully-Specified Name | |||
| component | Treponema pallidum Ab.IgG | ||
| 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^Donor Ser = Serum | ||
| scale | Ord = Ordinal: Ordered categorical responses, e.g., 1+, 2+, 3+; positive, negative; reactive, indeterminate, nonreactive. | ||
| method | IA = Immunoassay: Encompasses all immunoassays with a few exceptions, including Immune Blot and Immune Fluorescence, which were created based on historic usage. | ||
Additional Names | |||
| short name | T pallidum IgG Ser Donr Ql IA | ||

| 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. | ||
