Specimen type:
Female endocervical, vaginal and urine specimens. Male urine and urethral specimens.
Preferred collection container:
Alternate Collection Container:
Aptima® Vaginal Swab Specimen Collection Kit
Special notes:
See GML Trichomonas vaginalis Collection Guide. See Microbiology Collection Appendix for collection instructions. Check expiration date on transport device before use. For specimens collected in listed collection devices/kits, follow instructions provided. For Aptima® Unisex Swab Collection Kit (preferred device), use blue-shafted swab only. For Aptima® Vaginal Swab Specimen Collection Kit, use pink-shafted swab only. NOTE: The Aptima® Vaginal Swab Specimen Collection Kit is the only collection kit approved for vaginal specimens. This is not the primary collection device for GML. This test cannot be added onto a urine specimen that has already been submitted to the laboratory for testing. A fresh urine collection is required. You can add on a CTA, GCA or TVGA on a urine specimen that has either one of these tests already ordered.
