Endocervical swab- Use cobas PCR Media Dual Swab Sample Kit: With large cleaning swab, remove excess mucus and blood from the cervical os and surrounding mucosa and discard. Insert the flocked specimen collection swab into the endocervical canal and gently rotate the swab 5 times in one direction. Do not over-rotate. Carefully withdraw the swab avoiding any contact with the vaginal mucosa.  Immediately place swab into transport tube. Carefully break the swab shaft at the score line. Recap and Label tube with patient information/source/date/time.

Vaginal swab - Use cobas PCR Media Uni Swab Sample Kit: Hold the swab with the scoreline above your hand and insert the swab about 5 cm (2 inches) into the vaginal opening. Gently turn the swab for about 30 seconds while rubbing the swab against the walls of the vagina. Withdraw the swab carefully. Immediately place swab into transport tube. Carefully break the swab shaft at the score line. Recap and Label tube with patient information/source/date/time.

Rectal swab - Use cobas PCR Media Uni Swab Sample Kit. Hold the woven swab with the scoreline above your hand.Insert the swab about 3 to 5 cm (1-2 inches) into the anal canal. Gently turn the swab in a clockwise direction for about 5-10 seconds while rubbing the swab against the walls of the rectum. Withdraw the swab carefully. If the swab is grossly contaminated with feces, discard and repeat the collection. Insert the swab into the collection tube and break the swab shaft at the score line. Recap and Label tube with patient information/source/date/time.

Throat swab - Use cobas PCR Media Uni Swab Sample Kit:  Holding the specimen collection swab with the scoreline above your hand, instruct patient to tilt head backwards, open mouth and say "ah."

Use only cobas PCR Collection kits. Unacceptable specimens include wooden swabs, eye swabs and swab specimens without a swab in transport media. Large white swab is for preparatory cleaning of the endocervix and is unacceptable for testing when the dual swab is used for endocervical samples.

Carbomer containing products should not be used during specimen collection as this may affect test performance.

Blood may interfere with the performance of this test. Please re-collect if sample appears bloody.

For rectal specimens, the presence of fecal material may also interfere with test performance. Please re-collect sample if necessary.
