Test Code
182717


Alias/See Also
BV (Sialidase), Tv (NAA), Vaginal Yeast (Culture)


CPT Codes
87102; 87798; 87905

Preferred Specimen
"Vaginal fluid
"


Minimum Volume
"Multiple swab specimens
"


Instructions
"Using transport swabs provided, collect vaginal fluid sample by contacting the lower one-third of the vaginal wall, rotating for 10 to 20 seconds to absorb fluid. Immediately place the swabs into the transport tubes. For the APTIMA® swab, carefully break the swab shaft against the side of the tube. Tightly screw on the cap.
"


Transport Container
"Copan double swab in Aimes liquid medium and APTIMA® unisex swab transport
"


Transport Temperature
"Maintain specimen at room temperature or refrigerate (2°C to 30°C).
"


Reject Criteria (Eg, hemolysis? Lipemia? Thaw/Other?)
"Specimen collected or transport other than previously described; unlabeled specimens or those with a discrepancy between the specimen label and the request form; APTIMA® Combo 2 (AC2) swab specimen transport tube with two swabs or swab not supplied by Ge


Methodology
"BV (sialidase) activity: chromogenic enzyme activity test; vaginal yeast culture: culture; T vaginalis by NAA: nucleic acid amplification (NAA) "

Limitations
"BV (sialidase) activity: Collecting specimens from the cervix should be avoided because (a) it might increase the risk to OB patients, and (b) cervical sialidase activity is usually higher than vaginal sialidase activity. Do not collect specimens from patients who have (a) used a vaginal cream or ointment product, (b) douched, or (c) used spermicides, vaginal lubricants, or feminine sprays within 72 hours of testing. If insufficient sample is collected or collected from a patient undergoing antimicrobial therapy, the test may yield a false-negative result.
"


Clinical Significance
"BV (sialidase) activity: Enzyme activity test for use in the detection of vaginal fluid specimens for sialidase activity, an enzyme produced by bacteria associated with bacterial vaginitis, including Bacteroides spp, Prevotella spp, and Mobiluncus spp, and some G vaginalis. In a recent study, Bradshaw et al demonstrated the test to be 88% sensitive and 95% specific.
