3.4 Sample application using direct finger stick sampling
Ensure that you have a large hanging blood drop on the finger. Apply the sample by
holding the finger and the hanging blood drop over the circular Sample Application
Area on top of the inserted Test Strip.
Allow the blood drop to touch the Sample Application Area of the Test Strip. The sample
must cover the entire Sample Application Area.
Blood will then be drawn by capillary action into the Test Strip.When the sample is
detected the Instrument will sound and a confirmation message will be displayed. The
Instrument display will prompt to close the door.
Dispose of the lancet in the appropriate clinical waste. Clean the patient’s finger with
a clean tissue and apply slight pressure. If you need to retest, use a new Test Strip and
lancet, and a different finger.
