Preventing sore fingertips Be sure to prick the side of your finger, not the pad. Pricking the end of your finger can be more painful. Though it may be a tempting way to produce more blood quickly, don’t squeeze your fingertip vigorously. Instead, hang your hand and arm down, allowing blood to pool in your fingertips.
Why is it important to wipe away the first drop of blood?
The first drop of blood from a lancing site contains a greater volume of platelets, which could make the lancing site seal up before enough blood was obtained for the test, and the dual wipe ensured a longer, larger flow of blood.
Can squeezing finger affect blood sugar?
(In general, guidelines advise against squeezing the finger too hard to get a blood drop because it may distort blood sugar readings.) Overall, the study found, clean hands are still key.

Can you use your thumb to check blood sugar?
That’s why most blood glucose meters now offer the option of using blood from the fingertips, palm, upper arm, forearm, calf, or thigh, with some limitations. Studies have shown that using the palm (at the base of the thumb) gives similar results to blood drawn from the fingertip and is less painful.
Can you use the same needle twice to draw blood?
Healthcare providers (doctors, nurses, and anyone providing injections) should never reuse a needle or syringe either from one patient to another or to withdraw medicine from a vial. Both needle and syringe must be discarded once they have been used.

The use of an expired lancet (drum) may cause an infection at the puncture site as the lancet may have lost its sterility. We guarantee 4 years of sterility from the date of sterilisation, so you have plenty of time to use up your lancets.
