Abstract
A gel body is provided with a reagent system which interacts with a sample portion which diffuses into the gel to change the transmissive properties of the gel. The gel body is used in an assay for various analytes, and preferably has a shape and index of refraction whereby a beam of light can be transmitted through the gel body by total internal reflectance.
