摘　　要：The pre-analytical steps in blood-based liquid biopsy,involving sample collection techniques and storage conditions,play a critical role in ensuring the integrity and reliability of collected samples.These steps have a directly impact on the accuracy and reliability of test results and are therefore of utmost importance.Mass spectrometry(MS)-based proteomics is an exceptionally powerful tool in the field of liquid biopsy.It enables the comprehensive analysis of the protein content within biological specimens,providing valuable insights into the underlying mechanisms and pathogenesis of diseases.In this study,we aim to explore the variations in the protein landscape between serum and plasma specimens and evaluate the impact of delayed centrifugation on LC/MS-analyzed protein profiles.We seek to provide recommendations on optimal pre-analytical protocols for MS-based proteomics studies.This will enhance the accuracy and reliability of liquid biopsy for precision medicine,ultimately leading to improved patient outcomes.
