Candida Vaginitis/Trichomonas Vaginalis (Aptima® CV/TV Assay) -IVD
TEST: CPT: 87481 (CV), 87661(TV)
Causes for Rejection
Expected Turnaround Time 1-4 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the report is sent to the ordering provider. Additional time should be allowed for confirmatory, or reflex tests.

Multitest Vaginal Swab:
Care provider specimen: Collect vaginal fluid sample using the Gen-Probe® Aptima® Vaginal Swab Kit by contacting the swab to the lower third of the vaginal wall, rotating the swab for 10 to 30 seconds to absorb the fluid. Immediately place the swab into the transport tube and carefully break the swab shaft against the side of the tube. Tightly screw on the cap.
Patient self-collection instructions: Partially open the package. Do not touch the soft tip or lay the swab down. If the soft tip is touched, the swab is laid down, or the swab is dropped, use a new Aptima® Vaginal Swab Specimen Collection Kit. Remove the swab. Carefully insert the swab into the vagina about 2" past the introitus and gently rotate the swab for 10 to 30 seconds, making sure the swab touches the walls of the vagina so that moisture is absorbed by the swab. Withdraw the swab without touching the skin. Immediately place the swab into the transport tube and carefully break the swab shaft against the side of the tube. Tightly screw on the cap.
Interference with the Aptima CV/TV assay was observed in the presence of the following substances: Tioconazole 6.5% Ointment (3% W/V, all analytes), Vaginal Moisturizing Gel (1% W/V, C spp; 5% W/V, C. glabrata; 3% W/V, TV), and Glacial Acetic Acid (5% V/V, C spp only)
Store and transport specimens at room temperature (15 to 30°C). DO NOT freeze.
Specimen with incorrect patient identification; unlabeled specimen; inappropriate specimen transport conditions; specimens received after prolonged delay from time of pickup (usually >72 hours); specimen leaked in transit; specimen in expired transport or incorrect transport device; specimens with inappropriate source for test requested; specimen with fixative or additives; Aptima® swab transport >30 days from collection; Aptima® swab specimens with incorrect specimen volume; Aptima® swab specimen without a swab; any non−Aptima® swab submitted in Aptima® transport device; wooden-shaft swab in transport device; transport device with multiple swabs; female urethral swab; bloody or grossly mucoid specimens; bacterial swabs; specimen in MDL OneSwab®, ProbeTec™ UPT transport; ProbeTec™ Q-swabs; UTM-RT
The Aptima® CV/TV assay is an in vitro nucleic acid amplification test for the detection of RNA from microorganisms associated with vulvovaginal candidiasis and trichomoniasis. The assay utilizes real time transcription-mediated amplification (TMA) to detect and qualitatively report results for the following organisms: • Candida species group (C. albicans, C. tropicalis, C. parapsilosis, C. dubliniensis) • Candida glabrata • Trichomonas vaginalis The assay differentiates between Candida glabrata and the Candida species group (C spp) by targeting the RNA component of RNAse P ribonucleoprotein; the assay does not differentiate among C spp. For Trichomonas vaginalis, the assay targets ribosomal RNA (rRNA) and differentiates the result from results for Candida glabrata and C spp. The assay is intended to aid in the diagnosis of vulvovaginal candidiasis and trichomoniasis on the automated Panther® system using clinician-collected and patient-collected vaginal swab specimens from females with a clinical presentation consistent with vaginitis or vulvovaginitis.
The performance of the assay has not been evaluated in adolescents less than 14 years of age.
A negative result does not preclude a possible infection because results are dependent on adequate specimen collection. Test results may be affected by improper specimen collection, technical error, specimen mix-up, or target levels below the assay limit of detection (LoD).
Performance with specimen types other than vaginal swab specimens has not been evaluated.
