Test Procedure

1.2
The VerifyNow system has been developed to provide a simple, accurate and reliable
means to measure platelet aggregation. This section provides an overview of the test
procedure.
Whole blood is collected from an indwelling catheter or from a peripheral site into a
vacuum collection tube. The tube is gently inverted five times and stored at room
temperature until use (up to 4 hrs, depending on the assay type). Refer to Chapter 6,
Patient Testing for more information on sample collection.
At the start of the test, the assay device is inserted into the instrument, and the sample
collection tube is gently inverted again several times and placed on the assay device,
requiring no cap removal, specimen preparation, or pipetting step. The instrument
automatically draws the sample from the vacuum collection tube into the assay device,
and proceeds with the analysis of the sample. The used device and tube are removed and
discarded. There is no blood handling required by the user. Results are reported within 2-
5 minutes, depending on the assay.
Refer to Chapter 5, Quality Controls and Chapter 6, Patient Testing for more information
on operating the instrument.
