Medical Diagnostic Laboratories (MDL) announced that an azithromycin resistance reflex assay for Chlamydia trachomatis is now available. The new molecular diagnostic sequencing assay can detect specific azithromycin-resistant Chlamydia trachomatis strains.

Chlamydia is the most frequently reported sexually transmitted disease in the United States and is caused by the bacterium Chlamydia trachomatis. Left untreated, a chlamydial infection can spread to a woman’s uterus and fallopian tubes, and cause pelvic inflammatory disease (PID), ectopic pregnancy, and infertility.  This test is now being performed at no additional charge for any positive Chlamydia trachomatis specimens that have been detected by MDL’s real-time PCR diagnostic assay.

MDL also offers molecular diagnostic antibiotic resistance testing for two other common sexually transmitted diseases: Neisseria gonorrhoeae and Trichomonas vaginalis.
