Proper blood sample collection and handling techniques for blood gas analysis
Arterial blood is one of those patient specimens most sensitive to pre-analytical errors. Improper patient assessment, sample device selection, collection or transport of an arterial whole blood sample intended for pH, oxygen and carbon dioxide analysis, can render inaccurate patient results and potentially lead to misdiagnosis or inappropriate treatment. To help ensure the arterial sample integrity, the CLSI Guidelines: GP43:A4 Procedures for the Collection of Arterial Blood Specimens and C46-A2 Blood Gas and pH Analysis and Related Measurements are excellent references to assist clinicians in proper sample handling technique.
Optimizing your clinical operations involves everything from selecting the correct sample device to proper sample handling to adequate mixing to immediate transport.
