Blood glucose monitoring: Milking the finger and using the first drop of blood give correct glucose values
People with diabetes on insulin therapy are often advised to discard the first drop of blood and to refrain from milking the finger when monitoring blood glucose. The first drop is thought to be diluted with tissue fluid with a suspected low glucose content. Milking might enhance the leakage of tissue fluid.

Furthermore, in the highly perfused skin of the fingertip the glucose content in blood and interstitial fluid should be almost the same.
