The key to the preparation of the whole blood test specimen is to fully and completely anticoagulant, so it is necessary to reverse 5-8 times as soon as possible after blood collection to prevent the formation of small blood clots. Especially when the ambient temperature of blood collection is higher than 25 ℃, the mixing of blood and EDTA must be timely and sufficient, otherwise it will easily lead to blood coagulation or local coagulation.
