Q: Which blood draw is preferred for lactic acid draw? 

Answer: Arterial

Lactate level differs substantially between arterial and venous levels. The arterial level is more representative for this purpose. Normal lactate level from venous blood draw is 0.5 to 2.2 mmol/L, and from arterial blood draw is 0.5 to 1.6 mmol/L.
