Impact of delayed centrifugation on the stability of 32 biochemical analytes in blood samples collected in serum gel tubes and stored at room temperature

A delay in centrifugation of samples affected the stability of several analytes evaluated in the study, resulting in changes in their concentration or integrity. The analytical results for these analytes cannot be considered reliable as they do not meet the standards required for clinical validation. This underscores the importance of following stringent pre-analytical protocols to maintain the accuracy and reliability of laboratory diagnostic results.
