The review assesses the accuracy, reliability, and clinical utility of point-of-care testing compared to central laboratory testing for specific physiological parameters.
Comprehensive search of biomedical databases from 2015 to 2025.
Evaluation of observational evidence regarding the validity of blood gas analysers versus laboratory auto-analysers.
Focus on high-acuity settings including emergency departments and intensive care units.
POCT offered superior turnaround times compared to central laboratories.
Electrolyte measurements showed acceptable concordance, while haemoglobin and haematocrit lacked interchangeability during massive transfusions.
Precision of lactate measurements decreased at higher concentrations, raising the risk of clinical misclassification.
