Methods and devices are provided involving an inlet port, at least one chamber, a channel providing access for fluids to flow through via capillary action or differential pressure, reagents, detection means and self-venting materials. The devices allow for the appropriate mixing, reacting, incubating needed to give a detectable signal which can be read. The self-venting materials allow for the 1) displacement of gases inside a track to the outside of the device and 2) oxygen movement into the track from the outside.

A method for detecting the presence or an amount of an analyte in a test sample, comprising providing: (a) an analytical device comprising: a housing made of a hydrophobic material, said hydrophobic material consisting of: acrylics, polycarbonates, polystyrenes, silicones, polyurethanes, polyolefins

A method for detecting the presence or an amount of an analyte in a test sample, comprising providing: (a) an analytical device comprising: a housing made of a hydrophobic material, said hydrophobic material consisting of: acrylics, polycarbonates, polystyrenes, silicones, polyurethanes, polyolefins, polytetrafluoroethylenes, polypropylenes, polyethylenes, thermoplastic elastomers, copolymers, acrylnitrylbutadienestyrene, and styreneacrylonitrile; said housing containing an inlet port, said inlet port accessing a track of predetermined width and length within said housing and having at least one reagent therein; said track having at least one hydrophobic surface modified to create a hydrophilic surface by introducing at least one hydrophilic group onto said hydrophobic surface, said hydrophilic group consisting of: hydroxyls, carbonyls, carboxylics, aminos, sulfonics, sulfonates, sulfates, pyrroles, acetates, acrylics, carbonates, amidos, and phosphates; said hydrophobic material being impermeable to said test sample and allowing gaseous exchange in and out of a portion of said track; (b) adding said test sample to said housing through said inlet port; said test sample and said reagent producing a detectable signal upon mixing; and (c) determining the presence or an amount of an analyte in said test sample from said detectable signal.
