Lancets are part of every test for diabetes patients, even if they perform the test at home or hospital. This sharper needle helps take the blood required by pricking the site from where the sample is acquired.

Why can’t Lancet be Used Twice?

When the lancet is used repeatedly, the sharpness tends to diminish with time; this will cause severe pain in taking blood samples, as it crushes the nerve endings in your fingers. Tips of the lancet also have the chance to bend, causing a deeper wound while puncturing the fingertips.

It is always better to change the lancets after every use as it can have some remains of the blood sample taken. But studies don’t prove that by the reusing of lancets, the patient can get infections.

But most of the users don’t follow the idea of replacing the lancets regularly prefer to use the old lancet for some more tests. At hospitals, each time after using the lancet, it is disposed of properly to avoid using it on other patients.
