Abstract

Objective: To categorize and calculate the percentage error of pre-analytical variables in the clinical biochemistry laboratory. Methodology: Prospective observational study conducted for two months with documenting the frequency and type of pre-analytical errors occurring in venous samples. Result: The total errors recorded were 1.31%. Insufficient volume followed by haemolysis amounted to a major proportion of errors. Conclusion: Continuous pre-analytical phase evaluation and taking corrective measures to make this phase error-free, have to be done.   Keywords: Pre analytical error, Hemolysis, Insufficient sample volume.
