The comparison of BUN and CK between blood serum and anticoagulation blood plasma with EDTA of athletes

Objective To compare blood urea(BUN) and creatine kinase(CK) between blood serum and anticoagulation blood plasma with EDTA of athletes and to provide reference for the biochemical test in sports field.Methods 24 rowers were tested for 3 times according to the training and monitoring plan of the coach.and the athletes were given a necessary break everytime before the test day.After taking 1 mL blood from elbow veins at rest with an empty stomach,we separated them into two parts:EDTA anticoagulant tubes and centrifuge tubes.Ordinary blood test was done in the anticoagulation blood plasma group.The blood serum group was natural coagulation.At last the serums of both two groups were obtained after centrifuge.The level of BUN and CK were measured by automatic biochemical analyzer.Paired t test was done with SPSS Statistics V17.0.The significance was P0.05.Results There was no significant difference about both BUN and CK between the two groups(P0.05).Conclusion It is feasible that biochemical assay of BUN and CK with EDTA(EDTA-K2,EDTA-K3) anticoagulant blood plasma instead of blood serum.It has many advantages,such blood free,quick speed,simplifying the process of taking blood and economizing experiment instruments.It is more acceptable to athletes.It is worth popularizing.
