1. A transdermal dosimeter for use in a diagnostic test which comprises:
- (a) a sealed container constructed of chemically intert, flexible, fluid-tight, adhesive material;
(b) a dermal contact bridge in the container which comprises a fluid component and a support means component for supporting the fluid component within the container;
(c) a collecting component means in the container and in contact with the dermal contact bridge, for providing storage for fluid substances collected from the dermal contact bridge, said collecting component means being impregnated with an osmotically active crystalloid material; and
(d) a process component in the container made of fluid absorbent material containing a chemical reagent which reacts with the stored substances, said process component being in contact with the collecting component.
