Abstract:
Objective To observe the interference and influence of sample hemolysis on biochemical test results and to make cor-responding countermeasures based on the research results .Methods There were 58 cases of people who underwent physical exami-nation in the hospital .They were selected as study objects .Sample of venous blood was 5 mL in fasting .After natural coagulation and centrifugation ,K+ ,Na+ in blood were measured ,followed by the TP ,CK ,CK-MB ,AST ,ALB ,TG ,HDL ,LDH ,HBDH and other biochemical indexes .Then all indexes mentioned above were detected again after the sample hemolysis of serum ,and analysis results were compared between them .Results Of biochemical indicators detected before and after the determination of hemolysis , there were of statistical significance in the differences in K + ,Na+ ,TP ,CK ,CK-MB ,AST ,LDH and HBDH(P<0 .05);but there were no significant differences in biochemical indicators like ALB ,HDL and TG(P>0 .05) .Through regression analysis ,biochemi-cal indicators such as K + ,Na+ ,TP ,CK ,CK-MB ,AST ,LDH and HBDH were found to be related to hemolysis .Conclusion Sample hemolysis has certain influences on the results of biochemical test in terms of K + ,Na+ ,TP ,CK ,CK-MB ,AST ,LDH and HBDH , which is of certain application value with the proofreading of serum Hb concentration .
