The study aims to measure sample rejection rate, identify reasons for sample rejection, evaluate the effect of a campaign to reduce rejection rates and discover which clinical units produced the most insufficient specimen.

Methods: The study measured specimen rejection rates and the contributions of different rejection reasons in calendar 2016 and April 2018-March 2019.
