Abstract
Methods and compositions are provided for measuring an analyte without instrumentation. The device employs a stripstick which may include as its components, a discontinuous flow path, which is made continuous after transfer of the sample, means for automatically metering the volume of a sample, and means for providing a sharply delineated color front. The method finds particular use where a limited amount of substrate is provided for an enzyme on a sample pad.
