The median cubital vein is best for venipuncture because it is generally the largest and best-anchored vein.
The medial cubital or celphalic
Venipuncture is a medical procedure of puncturing a vein with a needle, usually to obtain a blood sample for testing or to administer medications or intravenous fluids. It is commonly performed by healthcare professionals like phlebotomists, nurses, or doctors.
the vein thats most subjected to venipuncture is located in the Antecubital fossa (the inner bend of the elbow) in the median antecubital vein(median cubital)
You use your thumb to keep the vein from "rolling" while doing a venipuncture.

The small saphenous vein is not typically used for venipuncture. This vein runs along the back of the leg and is deeper and more difficult to access compared to other veins, such as the median cubital vein in the arm. Additionally, it is primarily used for venous drainage of the lower limb rather than for blood draws. Venipuncture is usually performed on veins that are more superficial and easier to palpate.
When selecting a site for venipuncture, it is best to start with the veins running through the antecubital area. First, locating the Median Antecubital Vein, Cephalic Vein, and Basilic Vein. If unsuccessful with venipuncture, then approaching the dorsum of the hand, and lastly the dorsum of the foot.
