Results may be affected in the following situations: hemolysis, traumatic draw, pumping fist during draw, extended delay between drawing and testing specimen, exposure to air when measuring blood gases, and obtaining specimen from an arm with an IV.
Samples collected without anticoagulant must be tested immediately, within 3 minutes of draw time. Samples collected in anticoagulant must be tested within 10 minutes of draw time. Expel air bubbles and thoroughly mix syringe samples for >30 seconds by repeatedly inverting and rolling syringe immediately after sample collection.
