Label Mnemonic: CDNA
Epic Lab Code: LAB7688
Downtime Form: A-1a Miscellaneous Request
Commercial Mail-out Laboratory
5231 RCP
356-8593
Specimen(s):
Eye Swab
Specimen Instructions:
1. Discard the APTIMA Cleaning Swab (Female).

2. Swab site using APTIMA Collection Unisex Swab.

3. Place swab in transport tube provided in collection kit. Snap off swab at score line so swab fits into closed tube.

4. Cap tube securely, and label tube with patient's entire name, and date and time of collection.

Swab specimen must be collected using an APTIMA Collection Unisex Swab. These swabs are contained in the APTIMA Collection Kit.

Contact Specimen Control at 356-3527, Commercial Mailouts at 356-8593 or the IRL Lab at 467-2010 for collection kits. Some kits are located in the Special Care Nurseries Laboratory for immediate use.
Collection Medium:
APTIMA® Unisex Swab Kit
Testing Schedule:
Test performed Monday through Saturday, varies.
Turn Around Time:
1-3 days upon receipt at reference laboratory.
Reference Range:
Negative
Interpretive Data:
A positive result indicates the presence of rRNA Chlamydia trachomatis. This assay does detect plasmid-free variants of Chlamydia trachomatis.

A negative result indicates that rRNA for Chlamydia trachomatis was not detected in the specimen.

The predictive value of an assay depends on the prevalence of the disease in any particular population. In settings with a high prevalence of sexually transmitted disease, positive assay results have a high likelihood of being true-positives. In settings with a low prevalence of sexually transmitted disease, 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.
Comments:
Useful For:
Detection of Chlamydia trachomatis

Cautions:
This report is intended for use in clinical monitoring or management of patients; it is not intended for use in medico-legal applications.

Appropriate specimen collection and handling is necessary for optimal assay performance.

Results should be interpreted in conjunction with other laboratory and clinical information.

A negative test result does not exclude the possibility of infection. Improper specimen collection, concurrent antibiotic therapy, presence of inhibitors, or low numbers of organisms in the specimen (ie, below the sensitivity of the test) may cause false-negative test results.

In low-prevalence populations, positive results must be interpreted carefully as false-positive results may occur more frequently than true- positive results in this setting.

In general, this assay should not be used to assess therapeutic success or failure, since nucleic acids from these organisms may persist for 3 weeks or more following antimicrobial therapy.

This assay does not detect Chlamydia pneumoniae.
