Abstract
A reagent test strip (10,10') includes a support medium (12,12') having a handle portion (14,14') and a reagent support portion (16,16'). A reagent (18,18') is fixedly adhered to the reagent support portion (16,16'). A cover (20,20') is mounted on the support medium (12,12') and over the reagent (18,18'). The cover (20,20') defines a capillary chamber (28,28') having two open ends (30,30') and a predetermined volume only over the reagent surface (19) for drawing a predetermined amount of liquid (32,32') into the capillary chamber (28,28') to quantitatively react all of the liquid with the reagent (18,18'). The cover (20,20') is the only structure over the reagent surface (19,19') and is spaced thereover only sufficiently to establish the predetermined volume for acting as a capillary. Methods of using and manufacturing the reagent test strip (10,10') are also disclosed.
