Blood glucose test. Close up of a woman using a pen-like lancing device to prick her finger before a blood glucose test. Diabetics have to perform this test regularly.

Monitoring of blood glucose levels allows diabetics to control the disease through diet, medication and in some cases insulin injections. The pen is designed to make drawing blood less painful. color image,photography,people,one person,horizontal,adult,one woman only,adults only,holding,healthcare and medicine,human body part,close-up,human hand,examining,human finger,pen,lance,scalpel,diabetes,blood sugar test,prick,home health,lancing,pricker,home testing,draw blood
