ABSTRACT:
An assay for determining the cholesterol level in a sample involving a bibulous strip comprising a transfer region for transporting a transport medium from a transport medium source, a sample receiving region in fluid communication with the transfer region, and a measurement region in fluid communication with the sample receiving region, and a detectable signal reagent system comprising a catalytic agent or enzyme, unbound conversion reagent and bound reagent wherein the conversion reagent reacts with cholesterol to form an intermediate product and wherein the bound reagent reacts with the intermediate product in the presence of the catalytic agent or enzyme to produce a detectable border, in which the conversion reagent is placed in the transfer region of the strip or in a region of the strip between the sample receiving and measurement regions and the signal reagent is non-diffusively bound to the strip in the measurement region, and which upon contact with the sample and the transport medium results in the production of a detectable border in the measurement region which is related to the level of cholesterol in the sample.
