Abstract:
Objective To study the influence of different placing time of child peripheral blood on blood routine parameters in order to increase the working efficiency of clinical blood routine test.Methods Each 300 μL of peripheral blood was collected from the right hand ring finger in 50 healthy children in our hospital from January 2015 to January 2016.The blood routine was performed by using the whole blood cells analyzer at instantly after blood collection,at 0,5,10,15,30 min after blood collection under the room temperature (20 to 25 ℃).Results With the measured results at 15 min as the control,the detection results at the other times points had no statistical difference (P>0.05).Compared with the detection results at 5 min,the white blood cell count(WBC) and platelet volume distribution width (PDW),lymphocyte absolute value (LYM),neutrophil percentage absolute value (NEU),platelet count (PLT),red blood cell volume distribution width (RDW),hemotocrit (HCT) and plateletcrit(PCT) were statistically different (P<0.05).Conclusion Reasonably arranging time,eliminating pre-analysis error and reducing the influence of peripheral blood placing time on blood routine parameters have an important significance to accurately judge the clinical dat.It is recommended that the blood routine detection time should be controlled within 10-30 min in order to increase the working efficiency of clinical detections.
