Where will blood be drawn from a newborn for genetic screening?

Blood for genetic screening in newborns is typically drawn from the heel. This method is preferred because it is less invasive and reduces the risk of complications associated with venipuncture. The heel prick method allows healthcare providers to obtain a small sample of blood needed for various metabolic and genetic screenings.

Using areas such as the inner elbow or wrist for drawing blood can be more complicated in newborns due to their tiny veins and the need for more advanced techniques, which may increase discomfort and risk for the infant. The scalp is also not a typical site for blood draws in newborns. Therefore, the heel offers a safe and effective location to collect the essential specimens required for screening.
