Studies show the preanalytical phase of blood gas testing to be the phase most prone to errors.
Automatic mixing helps you mitigate preanalytical errors – such as insufficient mixing – by removing many of the operator-related variables that may lead to non-homogeneous samples.
Radiometer's automatic mixing solution does not cause hemolysis.
Studies show that manual mixing may causes random bias. Automatic mixing may minimise unnecessary testing while ensuring homogeneous samples and enabling accurate hemoglobin results; a cornerstone of costly decisions around red blood cell transfusions (RBCT) [1] (see Figure 1).
Automatic mixing is efficient, with samples mixed in approximately eight seconds (ABL90 and ABL800). In comparison, current recommendations from the CLSI (Clinical Laboratory Standards Institute) for manual mixing, are to gently mix the sample for a minimum of one minute.
Figure 1. Bland-Altman plots. Bland-Altman plots of agreement in the measurement of hemoglobin given by the ABL90 FLEX for manual (A) versus automatic mixing (B) in reference to Sysmex. Hospital color coding: Adventist Bolingbrook, (Green); Adventist GlenOaks (Blue); Adventist Hinsdale (Bordeaux); Adventist LaGrange (Red); University of Minnesota (Yellow). The main difference (solid line) and the CLIA allowable total error acceptability limits for hemoglobin of 4% (dotted lines) are shown. [1]

Blood gas syringes and capillary tubes
Radiometer capillary tubes, aspirating and self-fill blood gas syringes are designed with various features that are intended to reduce the risk of preanalytical errors.
1st Automatic
Pre-barcoded syringes help ensure correct patient-sample identification every time when using with a Radiometer blood gas analyser with 1st Automatic.
Blood gas testing
Radiometer offers a flexible blood gas diagnostic solution that can fit seamlessly into your acute care testing and hospital workflow.
Preanalytical blood gas errors
This handbook focuses on the preanalytical phase of blood gas testing and what you can do to minimise errors.
Patient blood management
Patient Blood Management is an evidence-based approach to optimising the care of patients’ blood. This includes opportunities to minimise blood loss and avoid the inappropriate use of blood.
