2937U: Neisseria gonorrhoeae Confirmation [TMA] Assay Urine Print View
N. gonorrhoeae TMA Conf Urine TMA  Not detected   

PRIMARY
1 Urine 5 (3) mL   Frozen - 3 Month(s)/Refrigerated - 30 Day(s)/Room Temperature - 30 Day(s) See COLLECTION INSTRUCTIONS./// 
ALTERNATE

The assay may be used to test specimens from symptomatic and asymptomatic individuals to aid in the daignosis of gonococcal urogenital disease, as well as to confirm the results obtained from the Gen-Probe APTIMA Combo 2 Assay (test code #7438U) for the simultaneous detection and differentiation of CT and/or GC.

a) The patient should not have urinated for at least 1 h
before specimen collection. Direct patient to provide a first
catch urine (approximately 20-30 mL of the initial urine stream)
into a urine collection cup free of any preservations.
Collection of larger volumes of urine may result in specimen
dilution that may reduce test sensitivity. Female patients
should not cleanse the labial area before providing the specimen.
b) Remove the cap and transfer 2 mL of urine into the urine
specimen transport tube using the disposable pippete provided.
The correct volume of urine has been added when the fluid level
is between the black fill lines on the urine transport tube
label. Re-cap the urine specimen transport tube tightly.
c) Urine in APTIMA urine specimen transport tube can be
transported 2-30 C. Urine in orginal collection transport
container can be shipped ambient, refrigerated or frozen.
Urine in original collection transport container shipped
ambient or refrigerated must be transferred to APTIMA
urine transport tube within 24 hrs.

Notes
The Gen-Probe analyte-specific reagent (ASR) APTIMA GC assay is a target amplification nucleic acid probe test that utilizes target capture for the in vitro qualitative detection of ribosomal RNA (rRNA) from GC in endocervical and male urethral swab specimens, and in female and male urine specimens. Recently, revised CDC guidelines for CT and GC testing recommended that a confirmatory test be performed following a positive screening test in order to imporove the specificity of a final diagnosis, especially in low prevalence populations. All positive tests should be considered as presumptive evidence of infection. Consideration should be given to increasing specificty by performing a confirmatory test after a positive screening test and requiring that both the screening test and the confirmatory test be positive to make a diagnosuis of CT or GC infection.
