Several methods are available for the detection of N. gonorrhoeae in clinical specimens. These methods include: Observation of gram-negative intracellular diplococci in gram-stained smears of urethral discharges from men and of endocervical secretions from women; Growth of N. gonorrhoeae from the urethra (men) or endocervix on selective culture media followed by demonstration of typical colonial morphology; And/or detection of N. gonorrhoeae with non-culture laboratory tests. A definitive diagnosis of gonorrhea requires: Isolation of N. gonorrhoeae from the sites of exposure by culture; Demonstration of typical colonial morphology, a positive oxidase test, and typical gram-negative morphology; and finally, a confirmation by specific identification methods. These confirmation methods may include acid production from carbohydrates, rapid enzyme tests, serologic assays, and tests for specific nucleic acids, such as is performed by the CT/NG APTIMA(R)TMA Assay.

SWABS: Swab must be submitted in Aptima(R) Combo 2 Assay
Unisex Swab Specimen Collection Tube. Follow instructions
in the Aptima(R) Combo 2 Assay Unisex Swab Specimen
Collection Kit for Endocervical and Urethral Swab Specimens
package insert.
In females, to ensure collection of an adequate specimen,
columnar epithelial cells lining the endocervix should be
obtained. To that effect, excess mucus should be removed
prior to sampling by using the white shaft cleaning swab
which is discarded after use.

COLLECTION CONTAINER: Gen-Probe Aptima(R) Combo 2 Assay
Unisex Swab Specimen Collection Kit.

URINE: Urine MUST be submitted in Aptima(R) Combo 2 Assay
Urine Specimen Collection Tube within 24 hours of collection.
The patient should not have urinated for at least one hour
prior to specimen collection. Direct patient to provide a
first-catch urine (approximately 20-30 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. Female patients should not cleanse the labial
area prior to providing the specimen. Thus, a urine sample
collected from a female for Chlamydia/GC TMA cannot be collected
at the same voiding event as that urine which would be intended
for bacterial culture. Remove the cap of the Aptima(R)
Combo 2 Assay Urine Specimen Collection Tube and transfer
2 mL of urine into the urine specimen transport tube using the
disposable pipette provided. The correct volume of urine
has been added when the fluid level is between the black lines
within the clear pane on the urine specimen transport
tube label.
