The kit may consist of a specimen container(s) with or without an additive/medium (e.g., cell or nucleic acid preservative solution, Carey-Blair transport medium), collection assistive device(s) (e.g., blush, spatula), gloves, labels, and/or a return packing/envelope for submission/mailing to the clinical laboratory. This is a single-use device.
