Introduction

Test principle

The CoaguChek XS PT test strip contains a lyophilized reagent (reagent
in dried form). The reactive components of this reagent consist of throm-
boplastin and a peptide substrate. When a sample is applied, thrombo-
plastin activates coagulation, which leads to the formation of thrombin.
At the same time the meter starts to measure the time. The enzyme
thrombin cleaves the peptide substrate, generating an electrochemical
signal. Depending on the time elapsed when it first appears, this signal
is then converted by means of an algorithm into customary coagulation
units (INR, %Quick, seconds) and the result is displayed.
