The influence of blood sample placing time on the results of clinical biochemistry test / 中国生化药物杂志

ABSTRACT

Objective To analyze relevant mechanism of clinical biochemical test results with blood specimen placement time,and provide reference for clinical examination.Methods100 biochemical test specimen in our hospital were selected, Biochemical test data were analyzed at different storage time (1h, 3h, 6h, 24h) using automatic biochemical analyzer combined with electrolyte analyzer.ResultsThe results of blood 1H determination were taken as the test standard, and the blood samples were placed in 3h.The results showed that the contents of glucose and carbon dioxide were significantly decreased (P<0.05).Blood samples were placed 8h, serum potassium, glucose, carbon dioxide, alanine aminotransferase (P<0.05) were significant differences, blood specimens were placed 24h, there were significant differences of the indexes including blood glucose, potassium, carbon dioxide, alanine aminotransferase, alkaline phosphatase, total bilirubin, total protein, albumin, aspartate aminotransferase, serum potassium, alpha hydroxybutyrate dehydrogenase, lactate dehydrogenase (P<0.05).ConclusionThe blood sample placement time have a significant impact on some biochemical indicators, in view of the unstable factors should be detected in the blood sample 1h intact, to avoid delay condition assessment.
