Treponema pallidum IgG Ab [Presence] in Serum from Donor by Immunoassay

Active

Term 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.

Part Description

LP14042-3   Treponema pallidum
Treponema pallidum is a spirochaete bacterium. Pathogenic treponemes are classified based upon their clinical manifestations in humans: venereal syphilis, yaws, endemic syphilis and pinta. Nonpathogenic treponemes are often part of the normal flora of the genital tract, oral cavity or intestinal tract. Treponemal infections exhibit diverse clinical manifestations which are characterized by distinct clinical stages. Multiplication of the bacterium at the entry point causes the primary stage. Dissemination of treponemes to other tissues produces the second stage. After a latency period (up to 20 to 30 years), the tertiary stage develops. T. palladum subsp pallidum (venereal syphilis) is the most destructive subspecies and produces lesions in many bodily tissues including the central nervous system. Congenital syphilis may result in birth defects or fetal death. Venereal syphilis is sexually acquired except for congenital syphilis, which is transmitted to the fetus during the later stages of pregnancy. The other treponemes are acquired by close nonvenereal contact. Control of both venereal and nonvenereal disease is based upon surveillance and antibiotic treatment of contacts.

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.
