Abstract

Objectives: Assessment of specimen rejection rates is an important laboratory quality measure for laboratories because of a potential negative impact on patient care. Here, we examined reasons for specimen rejection at a single, tertiary care healthcare institution and propose a framework for designing an efficient intervention.

Methods: During a 1-year period, we identified all specimens rejected at our hospital and performed an analysis of a wide range of associated variables: reason for rejection, patient location, type of phlebotomist, tests ordered, priority status, collection container used, transport time.

Results: Clotted and hemolyzed specimens accounted for the majority of rejected specimens, but significant differences in reasons for specimen rejection existed between patient care areas. Eighty-five percent of rejected specimens came from the Emergency Department and eight other inpatient care areas. Registered nurses drew approximately 85% of rejected specimens, while laboratory phlebotomy staff drew only 4%.

Conclusions: While hemolysis and clotting are primary causes for specimen rejection, collection of all available data regarding specimen rejection data is essential for laboratories determining which factors are most significant causes of specimen rejection.

Keywords: laboratory management; laboratory quality assurance; specimen rejection rate.
