High discrimination between genotypes with 100% sensitivity for FV:Q506. Reduces need for PCR determination. Applicable to anticoagulant treated patients.
COATEST® APCTM RESISTANCE V
An APTT-based kit for screening of factor V-related APC resistance. The high sensitivity and specificity of the test for the factor V:Q506 mutation is obtained by prediluting the sample plasma with an excess of V-DEF Plasma. The test design makes it possible to discriminate between heterozygous and homozygous factor V genotypes. It also allows for analysis of plasma from patients on heparin or oral anticoagulant therapy.
Measurement Principle
One volume of plasma is prediluted with four volumes of V-DEF Plasma. The dilution is then incubated with the APTT reagent for a standard period of time. Coagulation is triggered by the addition of CaCl2 in the absence and presence of exogenous APC and the time for clot formation is recorded.
