Quote from the Related Link: "Lancet: A small pointed knife; a surgical instrument with a short, wide, sharp-pointed, two-edged blade; a little knife with a small point.

Why should lancet be positioned across finger than parallel?
Positioning the lancet across the finger rather than parallel allows for a more effective blood sample collection. This technique minimizes discomfort by avoiding nerve endings and capillaries that are more densely located along the length of the finger. Additionally, it can facilitate better blood flow and yield a larger drop of blood, making the testing process more efficient. Overall, this positioning enhances both the comfort and accuracy of blood sampling.
Why would newborns cash in on so many red blood cells?
