RESUMO
Objective To explore the influencing factors of routine blood test results in the laboratory ,to ensure the accuracy of test results .Methods The influence of the different area of drawing blood and different testing time after blood collection were ob-served .Results The leukocyte count ,red blood cell count ,hemoglobin level of finger blood were obviously higher than those of venous blood ,and the platelet count was lower than that of venous blood ,the difference was statistically significant(P<0 .05) .≥6 h test specimens of blood platelet count was significantly lower ,compared to immediate detection and less than 6 h ,the difference was statistically significant(P<0 .05) .Conclusion The improvement of the system ,operation specification ,improving the quality of samples are helpful to improve the accuracy of test results .
