| WSLH Department: | CDD - Communicable Disease Division |
| WSLH Test Code: | SC00201 |
| Day(s) Performed: | Daily, Monday - Friday |
| Turn-around Time: | 1-3 days |
| Recommended Uses: | The Trichomonas vaginalis Assay is indicated for use with asymptomatic and symptomatic people (including itching in the genital area, a bad smelling frothy vaginal discharge, burning with urination, and pain with sex) to aid in the diagnosis of trichomoniasis. |
| Contraindications: | Self-swab specimens, patients less than 14 years, and specimens collected using swabs or kits other than those supplied for this assay will be rejected. |
| Additional Tests Performed: |
| Patient Preparations: | Follow instructions included with kit. Use only the collection materials supplied for this assay (with the exception of the primary urine collection device, not supplied.) |
| Specimen Requirements: | Prompt testing is highly recommended. Swabs in collection tubes should be stored at 2 to 30 C and analyzed within 60 days or frozen (=-20 C) and analyzed within 24 months. Urine must be transferred to an Aptima Urine Collection kit within 24 hours and be within the fill lines on the tube. After that it should be stored at 2 to 30 C and analyzed within 30 days or frozen (=-20 C) and analyzed within 24 months. |
| Specimen Handling & Transport: | Swab and urine specimens placed in collection kits may be transported to the laboratory at ambient temperatures. Use pressure-resistant bags as inner packaging for liquid (urine and swab) specimens. Avoid temperature extremes. |
| Collection Kit/Container: |
27 Yellow - Aptima Urine Collection Kit
29 Orange - Aptima Multitest Swab Collection Kit 29E White - Aptima Unisex Swab Specimen Collection kit |
| Collection Instructions: | Kit 29 (orange), Kit 29E (white), Kit 27 (yellow) |
| Unacceptable Conditions: | Specimens that have not been handled as described above will be rejected. |
| Requisition Form: |

| Results Include: | T. vaginalis rRNA detected, No T. vaginalis rRNA detected, or Invalid |
| Limitations: | A negative test does not exclude the possibility of infection. Positive results do not imply infectivity or treatment failure as residual rRNA may persist in the absence of viable organisms. |
| Additional Tests Recommended: | Additional testing may be recommended in cases where false-positive or false-negative results could lead to adverse medical or psychological consequences. |
| Additional Comments: |
