Abstract：Objective To investigate clinical blood test error and influencing factors. Methods Selected from 2014 July to 2015 January in our hospital treatment of 304 cases of patients blood routine examination samples, and detected blood routine samples in the different storage temperature, storage time, anticoagulant concentration conditions. Results When the storage temperature conditions for the normal temperature(6～25℃), white blood cell content was (4.42±0.63) ×109/L, significantly higher than that of 4℃ and platelet content was (210.41±7.93)×109/L, significantly lower than that of 4℃(P<0.05). The differences of red blood cell and hemoglobin in the conventional temperature and 4℃ was no statistical significance(P>0.05). After placing 4h white blood cell content was (2.92±0.77)×109/L, significantly lower than that of real-time and 2h detection value, and platelet content was (303.22±21.04)×109/L, significantly higher than that of real-time and 2h detection value (P<0.05). Real-time detection of red blood cell and hemoglobin content were (4.45±0.52)×109/L and (119.02±23.06)g/L, significantly lower than that of 2h and 4h(P<0.05). When the anticoagulants concentration was 2.4mg/ml, MCV and Hct were (89.32±7.05) fl and (0.441±0.012), significantly higher than that of the concentration of 1.6mg/ml and 2.0mg/ml. Conclusion Blood samples storage temperature, determination time and the anti coagulant concentration will affect the blood samples detection value, so the medical staff should test strictly in accordance with the relevant provisions.
