For your safety, never share a lancet with another person. These are sterile devices; do not use if protective disk has been damaged or removed.
Wash hands with soap and warm water. Dry well. Load lancet into lancing device and twist off protective cap. Choose a spot on the side of a different finger each time you take a blood sample. Follow lancing device manufacturer’s instructions for obtaining a blood sample. Eject lancet from lancing device and snap-on safety cap before discarding. To minimize the pain of testing, change lancet after every use to ensure the least painful puncture. Lancets become dull and painful when reused.
