Comments

Plasma from a sodium fluoride/EDTA tube can only be used for analysis of lactate and glucose. Failure to collect in fluoride tube may result in falsely elevated result. Warm puncture area before collection. Avoid any excercise of arm or hand during collection. Do not use tourniquet if possible. Collection tubes should be at least half-full.
