2.1.1 Assay Device Port and Cover
The assay device port holds a VerifyNow assay device during the test. When seated
in the port, the assay device is aligned with optical detection components to measure
the agglutination of the sample using light transmittance through wells in the assay
device. When closed, the assay device port cover blocks ambient light in the room
from interfering with the test.
The assay device port is also equipped with a spot code scanner that scans
information on the assay device to determine which assay is being performed and
the assay device lot number.
2.1.2 Display Screen
All messages and instructions for the operator display on the screen. The display
screen provides information about each step in the test, the assay type, mode, as
well as the current date and time. Figure 2-2 highlights the common features of the
software screens.
