Lancets are used to obtain a blood sample in order to test blood glucose levels. They can be used in conjunction with an appropriate device or may be designed for single use with the lancing mechanism being disposed of along with the lancet after use.
After use place protective cap on flat surface with round top facing down. Push lancet securely into the middle of the exposed side of the cap with thumb, push release button or plunger cap to expose lancet. Grasp lancet body and remove. Discard.
