Throat, conjunctival, or anal/rectal specimens are unacceptable for this test. Chlamydia/Gonorrhoea by Aptima (CTGC) is the only test that should be ordered for testing of these specimens. Test performed on FEMALE (urine, vaginal or endocervical) and MALE urine specimens. Urine samples: Patient should not have urinated for at least 1 hour prior to specimen collection. Patient should collect first portion of a voided urine (first part of stream- not midstream) into a screw-capped, sterile, plastic, preservative-free specimen collection container. Do not collect more than 20mL of urine. Females should NOT clean the labial area prior to urination. Swab samples: Large white swab is for preparatory cleaning of the endocervix and is unacceptable for testing. Specimen will be rejected if the APTIMA Swab Transport tube contains no swab, 2 swabs, or a non-Aptima kit collection swab. Vaginal, Enodcervical or Urethral specimens must be submitted in the Aptima Multitest Swab Specimen Collection Kit .Please place the label vertically and in the center of the transport tube.
