The effects of transfusion on the laboratory results
Objective:To investigate the effect of the blood sampling on the result of laboratory examination in the course of transfusion and to search for an appropriate time gap to obtain the unaffected examination result after transfusion.Methods:The subjects were divided into 4 groups
with 10 persons in each group.Blood samples were taken from all the subjects on empty stomach before transfusion
and then 500ml of 0.9%NaCl were administered intravenously on the forearm of the subjects.The 1st group
after 1h of transfusion
underwent the same side blood sampling in vein.The 2nd group
after 1h of transfusion
underwent
the other side blood sampling in vein.The 3rd group underwent the other side blood sampling in vein after transfusion.The 4th group underwent the other side blood sampling in vein
1h later after the finish of transfusion.RBC

ALP were tested.Results:The same side blood sampling during transfusion showed the greatest effect on the result of examination
with remarkable difference(P
<
0.05).The other side blood sampling during transfusion or after transfusion had the greatest effect on the result of many tests.Conclusion:Blood sampling during transfusion or after transfusion should be avoided.If for urgent need
blood sampling should be engaged in the other side of the infused limbs.
