Protein in body fluids, e.g., urine, is detected by contacting a sample of the body fluid with a diagnostic agent comprising an absorbent carrier impregnated with a pH indicator of the octahalosulfophthalein group, a buffer, and at least one linear or branched chain polypropylene glycol immiscible with water; the resulting test papers are highly sensitive to protein without being subject to interfering effects by nitrogen-containing compounds.

Coated tablets are prepared by applying to a core of active material, at least one layer of a coating composition made up of a film forming aqueous synthetic resin dispersion and from 2-50% by weight of a water or alkaline soluble material and thereafter permitting the coating composition layer to dry. The resulting coated tablet has a core surrounded by a continuous porous matrix of synthetic resin formed from the aqueous dispersion which is insoluble in water and insoluble in the gastrointestinal tract. The pores of the continuous resin matrix are filled with a discontinuous particulate material which is water or alkaline soluble. The coated tablet initially is air and moisture tight.

Glucose contained in urine is determined by contacting a sample with a diagnostic composition comprising an absorbent carrier impregnated with glucose oxidase, peroxidase, an indicator compound such as o-tolidine, and as a buffer, 2-(N-morpholino)-ethane-sulfonic acid.
