Methods for testing reagent distribution in reaction chambers

摘要

Apparatus and methods are disclosed for determining a functional property of a fluid in a chamber. A support to which is bound a plurality of test elements is introduced into the chamber. Each of the test elements comprises a reaction domain and a detection domain. A fluid that is interactive with the reaction domains is introduced into the chamber. Fluid is removed from the chamber. The locations at which the fluid has not interacted with the reaction domains is determined by means of the detection domains. The locations are then related to the functional property of the fluid.
