Abstract

The present invention relates to an assay apparatus for detecting a product in a sample (149). The assay apparatus comprises a fluid pathway with an input for the sample (14) and an input for a reagent (15) with a detectable moiety which transports the sample to a detecting means via a barrier (22) arranged to prevent a product-reagent complex passage but allow passage to the reagent and the sample. The complex is formed through interaction of the reagent and any of the product in the sample. The apparatus also including supply means for supplying a substance (24) adapted to breakdown the complex into a detectable moiety which can flow through the barrier to the detecting means (30).
