ABSTRACT:
A urine specimen maintenance formulation is provided which, when the urine specimen is added, maintains the specimen in the desired unaltered form for subsequent testing, without the need for refrigeration or other preservation measures, while simultaneously preventing any additional bacterial growth in the specimen. The formula of the invention includes distilled water, mannitol, boric acid and sodium borate. Additionally, the formula may include a buffer, such as sodium acetate, glutamine or other amino acids, and a surface active or dispersing agent to facilitate concentration of cellular elements during subsequent centrifugation of the sample for microscopic examination, as well as to facilitate preservation of organisms.
