Volume

One swab and one inoculated Jembec; or one swab

Container

Bacterial culture transport swab with gel and Jembec

Collection

Female: Do not use lubricant on speculum. Cervical mucus should be removed first before inserting swab into endocervical canal, move swab from side to side allowing several seconds for absorption of organisms by the swab. Return swab to the transport tube and label.

Clinical Information

Special Instructions

Specify specimen source and pertinent clinical information on the request form. Specimens from other sources, such as genital, stool, urine, upper and lower respiratory specimens, cannot be cultured under the aerobic bacterial culture test number. If specimens are incorrectly submitted with an order for aerobic bacterial culture, the laboratory will process the specimen for the test based on the source listed on the request form. The client will not be telephoned to approve this change, but the change will be indicated on the report. Check expiration date of transport; do not use expired devices.
