| Each single-use disposable assay device, such as the VerifyNow™ IIb/IIIa or VerifyNow™ Aspirin Assay, contains all needed reagents to provide analytical results for a specific assay. Assay devices are individually pouched and may be used until the expiration date printed on each kit box and foil pouch.
The assay device consists of the following components:
- Finger Grip: Each assay device has a handle with which the user can insert or remove the assay device from the assay device port.
- Staging Well: The blood sample is held in this area for temperature stabilization prior to analysis.
- Assay Device Spot Code: Each assay device is labeled with a unique spot code. Upon insertion of the assay device into the assay device port, the instrument automatically scans the spot code and determines which assay is being performed, records the lot number, and verifies that the assay device has not expired.
- Sample Well: The sample well is the area of the assay device where the blood collection tube is inserted. The well contains a Blood Collection Tube Spike for sampling directly from a closed blood collection tube. A protective sheath is removed from the assay device spike before use.
- Humidity Indicator: Each assay device has a humidity sensor to determine whether the assay device has been exposed to excess humidity.
- Mixing Chamber/Detection Wells: The wells contain all necessary reagents for the specific assays.
