A solid diagnostic device for the quantitative determination of substances of biological affinity in biological fluids is described. A process is also described in which the biological fluid is brought into contact with a specific functional sector of the device, the fluid migrates through several functional sectors situated beside one another and containing suitable reagent components, and one or more substances of biological affinity are detected in such functional sectors which contain, for each substance to be detected, at least one combination partner of biological affinity, attached to a solid phase.

Sheet-like diagnostic device

What are disclosed are polysaccharide derivatives of the formula ##STR1## in which n denotes a number from 100 to 12,500 and R denotes hydrogen, a carboxyalkyl or hydroxyalkyl group with 1 to 5 carbon atoms in the alkyl radical or a detectable molecular group, any combination of the (3n+2) R radicals being possible, but at least one R being a carboxyalkyl or hydroxyalkyl group and at least one R being a detectable molecular group, and a process for their preparation and their use for the determination of endohydrolases, in indicator paper and for the detection of metabolites in biological liquids, are described.

Method for determining the presence of endohydrolase in a liquid and

Diagnostic agents containing sodium nitroprusside are storage-stabilized by the presence of a compound having one of the formulas ##STR1## a cyclic compound of the formula ##STR2## wherein each A has the formula ##STR3## wherein X and Y are oxygen or sulfur and Z is oxygen, sulfur, or NH.

Diagnostic agent for the detection of ketone bodies

A test agent for the detection of coupling compounds in liquids is described, which essentially consists of an adsorbent matrix containing a diazonium salt as the reagent and a phosphonium salt to stabilize said test agent. Furthermore there is described a process for the preparation of said test agent.
