Specimen Type: Oropharynx/pharynx/throat
Supplies: Aptima Throat Swab Self-Collection Kit (T1002)
Container/Tube: Aptima Multitest Swab
Specimen Volume: Swab
Collection Instructions:
1. Specimens must be collected in a healthcare setting by the patient using the Aptima Multitest Swab (provided in T1002 or available separately).
2. Provide patient with the Aptima Throat Swab Self-Collection Kit or Aptima Multitest Swab and collection instructions.
3. Instruct patient to collect the specimen following the instructions provided and then return swab to the healthcare professional once complete.
4. Once patient returns the specimen, ensure the tube is securely capped, and label tube with patient's entire name and collection date and time.
5. Maintain swab container at either 4 to 30° C (refrigerated temperature is preferred) or -20 to -70° C, and transport within 60 days of collection.
Useful For
Detecting Chlamydia trachomatis using throat swabs collected by the patient in a healthcare setting

Negative
Interpretation
A positive result indicates the presence of nucleic acid from Chlamydia trachomatis.
A negative result indicates the absence of C trachomatis nucleic acid. A negative result does not exclude the possibility of infection. If clinical indications strongly suggest chlamydial infection, additional specimens should be collected for testing.
A result of inconclusive indicates that a new specimen should be collected.
The predictive value of an assay depends on the prevalence of the disease in any specific population. In settings with a high prevalence of sexually transmitted infections, positive assay results have a high likelihood of being true-positive results. In settings with a low prevalence of sexually transmitted infections, or in any setting in which a patient's clinical signs and symptoms or risk factors are inconsistent with chlamydial urogenital infection, positive results should be carefully assessed, and the patient retested by other methods if appropriate.
