As technology progresses, automatic analyzers substitute manual procedures and reduce analytical errors. However, as the number of test orders in hospitals and correspondingly as the number of sample accessioning in medical biochemistry laboratories increase, preanalytical phase of the total continuum becomes more inclined to errors. At present, vast majority of errors affecting test results occur in preanalytical phase (1). Among the tests studied, one of the most measured tests is complete blood count (CBC). Therefore, CBC is one of the tests which are numerically affected by the preanalytical errors (2). Management of preanalytical phase is difficult due to the need of participation of divisions other than the laboratory. Knowledge about variables impacting CBC test has a great importance for preventing preanalytical errors. Developing and complying with the instructions related to this issue are included in the responsibilities of the laboratory management. This reference document is prepared with the purpose of performing a useful, practical and applicable guideline for all medical laboratory staff, nurses, phlebotomists, students and researchers.
