Term Description
ARU See Aspirin Reaction Units
Assay device There are three types of assay devices relating to the appropriate
platelet function test: Aspirin, P2Y12, and GP IIb/IIIa inhibitors
(specifically abciximab or eptifibatide). Each single-use, assay
device consists of a sample well, staging well, and four detection
wells
Assay device The assay device port holds a VerifyNow assay device during the
port test.
Attention A type of message that displays after an unexpected event. These
events may be simple issues that can be easily addressed by the
customer.
Bar code A series of vertical black and white lines on the white assay
device package (pouch). The label stores information about the
assay type,
Bar code The bar code scanner scans a bar code on the white assay device
Scanner package, decodes the bar code, and passes the information to the
instrument software.
Base result For the P2Y12 assay, a base result using the Base channel
(TRAP and PAR-4 activating peptide) serves as an estimate of
baseline platelet function independent of P2Y12 receptor
inhibition. The Base result is normalized to report units that are
equivalent to baseline PRU.
Baseline A sample can be drawn prior to drug administration, and it can be
used as a baseline reading for determining percent inhibition (for
IIb/IIIa assay).
Cleaning device A single use, disposable plastic component with an adhesive strip.
The cleaning device is used to remove debris from a pneumatic
port connection inside the assay device port.
Clopidogrel Clopidogrel (trade name Plavix
oral antiplatelet agent used in the treatment of coronary artery
disease, peripheral vascular disease, and cerebrovascular
disease. As a thienopyridine, its mechanism of action is inhibition
of the P2Y12 receptor.
Cover A plastic door on the instrument that shields the assay device port
from ambient light.
