Mobile Clinical Branch

The Clinical Branch provides urine culture and sensitivity, syphilis, Chlamydia trachomatis, and Neisseria gonorrhoeae analysis for BCL healthcare providers. The Branch performs testing of clinical specimens within the compliance guidelines of the Clinical Laboratory Improvement Amendments (CLIA).

Syphilis Serology Section

The BCL’s syphilis screening procedure utilizes a multiplex flow immunoassay intended for the qualitative detection of total (IgG/IgM) antibodies to Treponema pallidum and the qualitative detection and/or titer determination of non-treponemal reagin antibodies in human serum or plasma. The preferred specimen is 3.5 ml of whole blood collected in a 13x75 mm serum separator tube.  If necessary, the specimen will be tested using a second treponemal test, the TP-PA (Treponema Pallidum-Particle Agglutination).

Chlamydia trachomatis/Neisseria gonorrhoeae (CT/GC)

The CT/GC/TV Section performs testing for Chlamydia trachomatis (CT), Neisseria gonorrhoeae (GC), and Trichomonas vaginalis (TV) using a single specimen by means of nucleic acid amplification technology (NAAT). Specimens for CT/GC may be of oral, cervical, vaginal, rectal, or urethral origin. TV testing is not available for specimens of oral or rectal origin. Specimens must be either swabs or urine collected using a Gen-Probe Aptima Combo collection device.

Urine Culture and Sensitivity Section

Urine Culture and Sensitivity is a state-wide program responsible for identifying and quantifying bacteria which can cause urinary tract infections. In addition, anti-microbial susceptibilities are given using modern instrumentation to provide accurate values for antibiotic treatment against these bacteria. Compliance with federal guidelines is employed following Clinical Laboratory Standards and the Clinical Laboratory Improvement Amendments (CLIA).

Proper specimen transport time is critical in maintaining the integrity of specimens, and specimen integrity may be compromised if they are not received in the laboratory within 48 hours after collection. Instructions for proper collection and transport are available to facilitate the accuracy of results.
