Abstract
This invention relates to means for transporting clinical specimens wherein the activity thereof can be retained for relatively long periods of time. The crux of the invention resides in a liquid reagent capable of preserving or stabilizing the activity of a particular specimen. Where the clinical specimen is Neisseria gonorrhoeae, the preferred liquid reagent consists of an aqueous mixture of cysteine and TRIS (Trihydroxymethylaminomethane) buffer. A convenient type of specimen collector comprises a swab. Again, where the clinical specimen is Neisseria gonorrhoeae, the preferred swab consists of calcium alginate. An apparatus particularly useful for transporting specimens comprises a screw-capped container having a liquid reagent sealed into the bottom portion thereof capable of preserving the activity of a particular specimen, and a specimen collector attachable to the inside of said screw cap through a longitudinal element of sufficient length to immerse said collector into said liquid. After a specimen has been obtained, the collector, attached to the screw cap, is forced through the seal into the liquid preservative as the screw cap is fastened tightly onto the container.
