The VerifyNow® Aspirin Test is a qualitative test to aid in the detection of platelet dysfunction due to aspirin (ASA) ingestion in citrated whole blood for the point of care or laboratory setting.
The VerifyNow® System is a turbidimetric based optical detection system which measures platelet induced aggregation as an increase in light transmittance. The system consists of an instrument, a disposable assay device and controls. The assay device contains reagents based on microbead agglutination technology. The assay device contains a lyophilized preparation of human fibrinogen-coated beads, platelet agonist, preservative and buffer. The patient sample is 3.2% citrated whole blood, which is automatically dispensed from the blood collection tube into the assay device by the instrument, with no blood handling required by the user.
