INTRODUCTION: The clinical laboratory testing process has three phases, and one of the most common errors that adversely affect the accuracy of laboratory test results occurs in the pre-analytical phase. Different brands of blood collection tubes used in laboratories can adversely affect the accuracy of the parameters. This study aims to compare the clot activator gel biochemistry tubes for selected clinical parameters.
METHODS: Fifty healthy volunteers aged between 18-70 years were included who didn't have any chronic or inflammatory disease, any clinical or pathological disease, and didn't use any medication. The biochemical parameters such as serum albumin, creatinine (crea), urea, triglyceride (TG), calcium (Ca), sodium (Na), potassium (K), and chloride (Cl) levels; aspartate aminotransferase (AST), alanine aminotransferase (ALT), and lactate dehydrogenase (LDH) activity were measured by an autoanalyzer. Student's t-test and Bland-Altman plot methods were used for statistical data analysis by SPSS software.
RESULTS: There was no statistical difference between the two different tube brands in terms of all evaluated clinical parameters that could affect the accuracy of the test results.
DISCUSSION AND CONCLUSION: When the BD® brand tube is taken as a reference, it is thought that AYSET® tubes give the same or close values, and the clinical use of AYSET® brand tubes will not cause an error in laboratory tests.
