The control solution is the little vial of liquid that might have come with your CONTOUR®NEXT meter and it's used to review the performance of your CONTOUR®NEXT meter and strips. You should perform a control test when using your meter for the first time, opening a new bottle or package of test strips, you think your meter may not be working right and when you have repeated, unexpected blood glucose results.
