Sensitivity of this method is dependent on adequacy of the smear. If there are fewer than 20 columnar epithelial cells, the result will be reported as "sample inadequate." Amplified DNA testing is recommended for detection of Chlamydia trachomatis from endocervical or urethral specimens. Refer to Chlamydia trachomatis by Amplified Detection (APTIMA®) (0060243). Specimen must be collected and transported with test-specific kit. Culture is recommended for Chlamydia trachomatis detection in suspected sexual abuse and for suspected failure of therapy. Refer to Chlamydia trachomatis Culture (Genital) (0065012). |
