For hours, walk-ins and appointments.HIV p24 antigen/antibody with reflex to antibody differentiation; HIV-1/2 qualitative RNA; T. pallidum antibody w/reflex to RPR (with titer); Chlamydia/Gonococcus, NAA; human chorionic gonadotropin (hCG), β-subunit, quantitative
This profile requires a dedicated, unopened, gel-barrier tube and a frozen (preferred) or refrigerated serum pour-off tube.
Note: Client must clearly label the site/source of each Chlamydia/Gonococcus Nucleic Acid Amplification specimen.
Tests included within this profile may exhibit interference when sample is collected from a person who is consuming a supplement with a high dose of biotin (also termed as vitamin B7 or B8, vitamin H, or coenzyme R). It is recommended to ask all patients who may be indicated for testing about biotin supplementation. Patients should be cautioned to stop biotin consumption at least 72 hours prior to the collection of a sample.
2 - 3 days (testing performed daily)
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Serum and first-void urine (patient should not have urinated for one hour prior to specimen collection) or endocervical or vaginal swab
5.5 mL serum and 2 mL of a 20 mL to 30 mL urine collection or one swab (endocervical or vaginal)
4.5 mL serum (this volume does not allow for repeat testing) and 2 mL of a 15 mL urine collection or one swab (endocervical or vaginal)
Gel-barrier tube and Gen-Probe® APTIMA® urine specimen transport or APTIMA® swab
Serum specimen: Usual blood collection technique.
Option 1: Gen-Probe® Aptima® Endocervical or Vaginal Swab
Endocervical swab: Remove excess mucus from the cervical os and surrounding mucosa using the cleaning swab (white-shaft swab in the package with red printing). Discard this swab. Insert the specimen collection swab (blue-shaft swab in the package with green printing) into the endocervical canal. Gently rotate the swab clockwise for 10 to 30 seconds in the endocervical canal to ensure adequate sampling. Withdraw the swab carefully; avoid contact with the vaginal mucosa. Remove the cap from the swab specimen transport tube and immediately place the specimen collection swab into the transport tube. Carefully break the swab shaft at the scoreline; use care to avoid splashing of the contents. Recap the swab specimen transport tube tightly.
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 and rotating the swab for 10 to 30 seconds to absorb 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: Partially open the package of the Gen-Probe® Aptima® vaginal swab kit. 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® swab specimen collection kit. Remove the swab. Carefully insert the swab into the vagina about two inches 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.
Option 2: Urine Specimen: The patient should not have urinated for at least one hour prior to specimen collection. Direct patient to provide a first-catch urine (approximately 20 to 30 mL of the initial urine stream) into a urine collection cup free of any preservatives. Collection of larger volumes of urine may result in specimen dilution that may reduce test sensitivity; lesser volumes may not adequately rinse organisms into the specimen. Female patients should not cleanse the labial area prior to providing the specimen. Add urine to the Aptima® Combo 2 urine collection device. The final volume must be between the two black lines on the device (about 2 mL).
PCR test: Centrifuge sample within 24 hours of collection. Transfer serum to a screw-cap polypropylene transport tube. Ship frozen (preferred) or refrigerated.
Serum: Gel-barrier tubes refrigerated up to 7 days
PCR test: Frozen up to 6 weeks
APTIMA® Swab or urine: Maintain at room temperature or refrigerate (2°C to 30°C)
Temperature | Period |
---|---|
Room temperature | Swab: 60 days; urine: 30 days (stability provided by manufacturer or literature reference) |
Refrigerated | Serum: 7 days (stability provided by manufacturer or literature reference) |
Frozen | Serum: 6 weeks (stability provided by manufacturer or literature reference) |
Freeze/thaw cycles | Serum: Stable x4 (stability provided by manufacturer or literature reference) |
Patient should not have urinated for one hour prior to specimen collection.
Hemolysis; lipemia; received outside of specimen and/or storage and/or labeling requirements; aliquot received for HIV testing; specimen in expired transport or incorrect transport device; specimens with inappropriate source for test requested; APTIMA® urine transport >30 days from collection; APTIMA® urine transport with incorrect specimen volume; APTIMA® swab transport >60 days from collection; APTIMA® swab specimen without a swab; cleaning swab (white-shaft swab) in APTIMA® swab transport; APTIMA® transport device with multiple swabs
This profile aligns with current guidelines for monitoring female patients on oral HIV PrEP.
The profile includes HIV Antibody/p24 Antigen and HIV-1/2 RNA for the detection of HIV infection; Chlamydia trachomatis and Neisseria gonorrhoeae nucleic acid amplification; serologic testing for syphilis; and assessment of pregnancy status.
HIV p24 antigen/antibody specimens with reactive results must be investigated by additional supplemental tests. A negative test for an individual does not preclude exposure to or infection with HIV-1 and/or HIV-2. Negative results can occur if the quantity of the marker present in the sample is too low for detection by the assay or if the marker is not present during the stage of disease in which a sample is collected.
