Several methods are available for the detection of C. trachomatis in clinical specimens, including giemsa staining of tissue, fluorescent antibody staining, culture, and nucleic acid detection. Although culture is very specific, it lacks sensitivity, so recommendations have been put forth to include multiple tests in assisting with a diagnosis of infection, including tests such as 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 Urethal 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.
