This box of 50 lancets is used with the iHealth lancing pen.
Lancets are ultra small needles slightly that are used to collect a blood sample. They are used with an iHealth lancing device that will adjusts the depth and strength of the needle so that the drawing of blood is virtually painless.
The drop of blood collected will be put in contact with the strips. The iHealth strip (link), inserted in the iHealth blood glucose meter, will measure the blood glucose by analysing the reaction between the blood and the strip.
