## Indications for use
Medifun Lancing Device, Model No. LD-E1 is a reusable lancing device for the single user. It should be used with the proper sterile lancet for the capillary blood sampling. It could automatically inject the lancet into and retract it from the fingertip to obtain a capillary blood sample for glucose monitoring or other test that require one or two drops of blood. A depth adjustable cap allows the best depth of skin penetration for each individual user. Alternative site testing (palm or forearm) can be performed by installing the clear cap on the lancing device.
