General questions
How can I make it easier to get a drop of blood?
There are a few ways you can improve blood flow and make blood sugar testing easier: Warm your fingers by washing with warm, soapy water, then rinse and dry completely. Let your arm hang down at your side to increase blood flow to the fingertips. Grasp finger just below the joint closest to the fingertip and massage gently toward tip of finger, then squeeze for 3 seconds. Use an Accu-Chek lancing device set to the right penetration depth for your skin type. Refer to your user guide for additional information.

General questions
Why does the test sometimes start even if yellow is still showing in the strip window?
The system automatically detects when enough blood has been applied to the strip and begins the test, even if some yellow is still visible. The only time you need to apply more blood is when the blood drop symbol continues to flash in the display.
