Methods and kits are provided for detecting analytes, which can be measured directly or indirectly by production of an enzymatic product. The enzymatic product reacts with a signal producing reagent bound to a bibulous strip. Various devices are employed for producing a reaction, directly or indirectly with the, analyte and then providing for migration of the product through the bibulous strip with reaction with the reagent to produce a detectable signal. The distance from a pre-determined site to the border of the detectable signal is a quantitative measure of the analyte in the sample.
