Quality Control Testing
Perform Quality Control Testing when:
• You first get your meter, before performing a blood glucose test.
• You first begin to use a new bottle of Touch-In
®
Plus Blood Glucose Test Strips.
• You suspect your GlucoSure
®
Plus Blood Glucose meter and Test Strips are not working properly.
• The blood glucose results do not reflect how you feel.
• When your Test Strips have been exposed to extreme temperatures (
see Touch-In
®
Plus Blood Glucose Test Strip Insert for operation ranges).
• Practice the test procedure.
Two levels of Contrex™ Plus Glucose Control Solutions are available for quality control
testing. Each level tests a different range of glucose concentration.
