Description
Date extension
When Accumetrics issues a date extension notification for a
specific lot of assay devices, these devices can be used after the
original expiration date.
Detection well
The detection wells of an assay device contain a lyophilized
preparation of human fibrinogen coated beads and platelet
agonist. The instrument measures platelet aggregation as an
increase in light transmittance through the detection wells.
Diluent
An optically absorbent solution used in lieu of blood during wet
quality control.
Diluent tube
Tube in the Assay WQC kit containing the diluent.
Discard tube
When collecting patient samples using direct venipuncture, the
discard tube (that is later discarded) is filled before the sample
tube. This tube may be plain sodium citrate, blood culture, or
heparin tube. The tube cannot contain EDTA (purple top).
Electronic
Electronic quality control (EQC) is a procedure during which the
quality control
software will calibrate and verify instrument optics performance,
reagent mixing, and instrument pneumatics.
EQC
See electronic quality control.
EQC device
A re-usable device that is inserted by the operator into the assay
port and is used to perform a comprehensive testing routine that
confirms performance of key instrument components.
EQC frequency
Specifies the time interval between EQC tests. When the time
interval is exceeded, the instrument cannot perform patient testing
until an EQC test is performed.
Eptifibatide
Eptifibatide (trade name Integrilin
inhibitor mainly used during and after coronary artery procedures
like angioplasty to prevent thrombus (blood clot) formation within
the coronary artery. Its mechanism of action is inhibition of the
glycoprotein IIb/IIIa complex.
Error
A type of message that displays after an unexpected event.
Typically these events occur when the instrument detects an
abnormal condition, and often can be corrected by the customer.
