Abstract
An over the counter swab kit for self detection of gonorrhea in the male using saline ampul. A method wherein a pledget in the form of fibrous material is impregnated with a compound which reacts with Neisseria gonorrhea to produce a color change. The pledget, before the test, is in a dry condition and is activated by a wetting agent such as saline, when placed in contact with the pledget. The chemical compound used and incorporated into the pledget is selected from a group consisting of phenylenediamines. A sufficient amount of saline is held within a frangible ampul to wet the pledget and then to be drawn by capillary action through the swab on which a sample of exudate as a specimen is placed. The chemical compound is in the form of a mineral acid salt which dissolves in the saline and is transported by capillary action through the pledget into the swab. A purple color is created on the tip of the swab at the site of the bacteria and is a positive test for gonorrhea. There is also disclosed a novel method for the manufacture of the novel swab kit for self detection of gonorrhea in the male.
