1. An integrated system for biological fluid constituent analysis, comprising:
- collector means for non-invasively collecting a body fluid analyte from a patient and indicator means responsive to the body fluid analyte for indicating a condition of the body fluid analyte;
electronic interpretation means receiving said indicator means and electro-optically interpreting said indicator means with regard to the condition of the body fluid analyte;
wherein said collector means are in the form of a multi-layer laminate including a chemical reactant layer coated with a test reagent and color developer specifically provided for a given test, an activation gel layer disposed below said chemical reactant layer, a collection gel layer disposed below said activation gel layer, and a skin interface membrane layer disposed below said collection gel layer for placement on the patient'"'"'s skin;
said indicator means being in the form of a color wheel, said color wheel being divided into a plurality of color segments each communicating with said multi-layer laminate for displaying a given color in response to a given amount of body fluid analyte processed through said layers.
