Part Descriptions

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.

LP6760-5   Wet preparation
A wet preparation or wet mount is used to identify the cause of vaginosis, a general term for infections of the vagina. A drop of vaginal discharge is placed on a slide with a drop of liquid –usually water--which is then examined microscopically as an unstained wet mount or as a Gram-stained slide. The refractive index of the water improves the image quality. Wet mounts generally cannot be stored since the water evaporates. Glycerol or immersion oil can be used instead of water. Bacterial vaginosis, candidiasis and trichomoniasis are common diseases which may be diagnosed through a wet preparation. [Lab Tests Online Conditions:vaginitis/start/2] Source: Regenstrief LOINC
