Abstract
This reagent strip is comprised of a testing portion which contains an absorbent cotton pad. This absorbent cotton pad may be placed in the mouth on the tongue to collect an oral fluid sample. A plastic frame surrounds the pad to help hold the fluid thereon. This testing strip contains at its opposite end a sealing mechanism for sealing engagement with a preservative pouch, and an oversized handle with a patient identifying mechanism. The preservative pouch of the present invention contains a pair of seals. The first seal, located proximally to the user, enables a preservative which is maintained within the pouch to be sealed during shipment of the pouch to the user. Thereafter, the user punctures the first seal upon placement of the reagent pad into the pouch. The sealing mechanism contained on the reagent pad then seals at the opening in the pouch to maintain the reagent pad in sealing arrangement within the pouch. At its distal end, the pouch contains a second sealing mechanism. This sealing mechanism helps protect the preservative as well as the oral sample, within the pouch during shipment from the user back to the testing laboratory.
