FreeStyle diabetes test strips were designed to prevent sore fingers after testing by requiring just a tiny blood sample which is the smallest in the world at just 0.3 micro-liters! Even with this small size of a sample FreeStyle ensures accurate test results every time that is virtually pain-free. This is due to a new, patented technology based on coulometric measurements.
 
The FreeStyle Test Strips use capillary action that acts like a sponge to wick the exact amount of blood needed onto the glucose test strip. You have up to a minute after the initial sample is taken to add more blood if needed. The diabetes test strips work with the blood glucose meter, which will then beep when there is enough of a blood sample for accurate test results.
