Part Description

LP14413-6   Trichomonas vaginalis
Trichomonas vaginalis (TV) is an anaerobic, flagellated parasitic protozoan that is among the most common non-viral sexually transmitted organisms whose only known host is humans. It is estimated that 170 million new cases occur worldwide and it is the most common sexually transmitted diseases in the United States. TV is known to increase HIV acquisition and transmission in both men and women by acting as a cofactor to increase susceptibility to HIV of an uninfected partner and infectivity of HIV of an infected partner. In women, infection with TV is a possible risk factor for developing cervical neoplasia, post-operative infections, adverse pregnancy outcomes, atypical pelvic inflammatory disease and infertility. In men, infection with TV can lead to non-gonococcal urethritis, infertility, chronic prostatitis and decreased sperm motility. Diagnosis is most often made using wet mount microscopy which has a sensitivity of only 52%. Other diagnostic methods include Pap smear, culture and PCR with sensitivities of 56%, 78% and 84%, respectively. There is an estimated 5 million new cases of TV annually in the United States and yet TV is still not a reportable disease. Treatment for TV is with metronidazole though emerging metronidazole-resistant strains have been reported. Asymptomatic infection can persist for months to years.

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.
