ABSTRACT:
The invention is a self-contained, chromatic quantitative analyzer that quantitatively detects an analyte in a biological fluid. The invention includes a base having a first open reservoir for receiving the biological fluid. A means for separating solids from the biological fluid is provided in the first open reservoir. A channel is provided which draws, by capillary and/or wicking action, the biological fluid from the first open reservoir to a second open reservoir. The second open reservoir draws the biological fluid from the channel and, when the second open reservoir is full with the biological fluid, the capillary and/or wicking action terminates. A membrane is provided in the channel which is permeable to the biological fluid. There is at least one chromatic chemical indicator immobilized in the membrane in a predetermined concentration. The membrane enables the biological fluid to interact with the chromatic chemical indicator.
