Device and method for measuring properties of a sample
First Claim
1. A test strip for determining the degree of the ability of a sample to coagulate comprising at least two branch channels each fluidly connected to a different reaction chamber, wherein at least one of said branch channels is a delaying branch channel and at least one of said branch channels is a non-delaying branch channel, wherein the delaying branch channel is adapted to delay arrival of a portion of the sample to its reaction chamber with respect to arrival of a second portion of the sample to said non-delaying branch channel reaction chamber, and further wherein at least one of said delaying branch channels is fluidly connected to a control reaction chamber, wherein at least one of said non-delaying branch channels is fluidly connected to an assay reaction chamber, and wherein the control reaction chamber comprises an electrode pair for measuring an electrical property of the sample.

Abstract
Test strips designed to prevent or reduce false results when measuring the condition of a sample are provided. The test strips can be used for analysis of samples by methods including electrical and optical measurements. The reagent test strips and methods are particularly suited for use in the detection of blood coagulation.
