Comments

• Testing of vaginal swab specimen requires use of Aptima Vaginal Swab specimen collection kit. • Testing of endocervical or male urethral swab specimens requires use of Aptima Unisex Swab specimen collection kit. Large white swab is for preparatory cleaning of the endocervix and is unacceptable for testing • Testing of male and female urine specimens: 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. • Testing of throat, conjunctival, or anal/rectal swab specimens requires collection using M4 Collection Kit (swab and M4 media).Culture for Chlamydia on such nongential specimens can be ordered on the same specimen. If a GC culture is also requested see GC culture collection procedure.
