Influence of preanalytical phase on biochemical laboratory results

There are many factors that contribute to accurate test results in the clinical laboratory. These factors can be divided into three areas:

preanalytical, analytical and post analytical. Preanalytical variables account for 32–75 % of laboratory errors. Haemolytic specimens

are the leading cause of preanalytical variability. Hemolysis is preventable in most cases, because it is usually caused by inappropriate

collection, handling and processing the specimen.

Keywords: preanalytical phase, interference, haemolysis
