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

1. Endocervical swab specimens:
a. Remove excess mucus from cervical os and surrounding mucosa
using cleaning swab (white shaft). Discard swab.
b. Insert the specimen collection swab (blue shaft swab in
the package with green printing) into the endocervical canal.
c. Gently rotate the swab clockwise for 10-30 sec in the
endocervical canal to ensure adequate sampling.
d. Immediately place the specimen collection swab into the
transport tube and re-cap the tube tightly.
2. Male urethral swab specimens:
a. Instruct the patient not to urinate for at least 1 hr
before specimen collection.
b. Insert the specimen collection swab (blue shaft swab in the
package with the green printing) 2-4 cm into the urethra.
c. Gently rotate the swab clockwise for 2-3 sec in the urethra
to ensure adequate sampling.
d. Immediately place the specimen collection swab into the
specimen transport tube and re-cap the tube tightly.
M4 media samples:
See manufacturer's collection instructions or call Client Services
for details. Swab in M4 media
can be shipped or stored at 2-30 C for 3 days. If longer storage
is needed, store at 20 C or 70 C for 60 days.
ThinPrep Pap Test Specimens:
Specimens collected using broom-type device and placed in Cytyc
PreservCyt Solution for use in making ThinPrep Pap Test slides can
be used for CT/GC testing. Collect specimens in routine manner; 4 mL
PreservCyt solution required for CT/GC test. PreservCyt specimens
stable 3 weeks ambient following collection and prior to processing.
Specimens in alternate transport media (M4, ThinPrep, SurePath,
culturette swabs) have been validated by Quest Diagnostics Nichols
Institute.

Notes
This analyte-specific reagent (ASR) Gen-Probe APTIMA CT assay is a target amplification nucleic acid probe test that utilizes target capture for the in vitro qualitative detection of ribosomal RNA (rRNA) from CT 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 improve 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 specificity 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 diagnosis of CT or GC infection.
