Abstract:Background: Time delays and mechanical stress of samples obtained for Point of Care (POC) blood gas analyses are common; however, their influence on the results of these analyses has not been systematically investigated. Our study aimed to investigate the effect of prolonged time before analysis and mechanical manipulation on pre-analytical stability of biomarkers and thus the validity of the results of blood gas analyses.
Methods: We collected blood samples from 240 patients in a university surgical intensive… Show more
