Abstract:
Objective To investigate the blood specimen collection site,inspection time and hemolysis influ-ence on biochemical test results.Methods The specimens of 2586 cases outpatients and hospitalized patients in our hospital who accepted blood routine and blood coagulation four check were analyzed.The hemolysis and qualified specimens of biochemical test results were compared.Results 2 586 specimens found unqualified blood samples in 18 cases,and the incidence rate was 0.70% (18 /2 586).Samples of different section and source were compared and found there were no significant difference (F =0.36,P >0.05).In 18 cases of unqualified blood samples due to technical problems and unqualified sample accounted for 88.89% (16 /18).The technical factors that lead to unqualified samples was significantly higher than that of the instrument factor or fixed factors,and the difference was statistically significant(χ2 =152.63,98.52,all P <0.05).In addition,hemolysis caused the most of the unqualified samples for the technical factors.To choose potassium infusion on the side ipsilateral to the site or from the opposite side of the site collected blood samples.Sodium,chlorine,creatinine,uric acid,glucose detection found in effect of blood on the same side of the infusion of the biochemical test results in varying degrees.Potassium,chlorine,sodium, creatinine decreased significantly,and uric acid,glucose and other indicators were significantly increased (t =4.51, 4.98,5.50,3.25,10.18,15.25,all P <0.05).Gamma transpeptidase,creatine kinase,sodium and uric acid and other index of hemolytic samples were significantly lower than those of normal samples,and alanine aminotransferase (ALT),direct bilirubin,potassium,phosphorus,serum creatinine and creatine kinase were significantly higher than those of the normal samples (t =14.85,21.21,7.15,4.86,10.33,4.02,3.11,8.20,7.54,5.11,all P <0.05).This may cause the depth in erythrocytes and some related substances.The time of collecting blood to sent to the room had obvious influence on the biochemical test results,alanine aminotransferase,aspartate amino transferase,glucose, creatine kinase and hydroxybutyrate and project them 1 h after submission were significantly lower than those of the standard inspection,and 1 hour after the submission of lactate dehydrogenase and creatine kinase isoenzyme index were significantly higher than those of the standardize inspection means (t =2.95,4.82,2.88,5.44,4.05,3.98, 4.89,all P <0.05).Conclusion Sampling sites,hemolysis and inspection time had effect on blood specimen,so for the collection of blood samples must be strictly in accordance with the requirements of the operation.
