Appendix A: Sample Collection and Handling
Caution
 Observe the general cautions required of the hospital, laboratory,
or other testing facility.
 All biohazardous materials should be handled and disposed of in
accordance with applicable rules and regulations.
 The blood and/or collecting tools, and used cartridges should be
treated as biohazardous materials.
 Wear appropriate personal protective clothing (lab coat, gloves,
goggles, etc.). And Be careful not to let the blood and/or
collecting tools directly touch the mouth, eyes, mucus
membranes, or any area with broken skin.
 Wash hands after collecting the sample or using the analyzer.
Sample
preparation
 Use whole blood to a blood gas test.
 To draw blood samples, use containers (syringe, capillary, blood
collection tube) treated with heparin. We recommend using a
dry-sprayed heparin tube or a solid heparin tube. We do not
recommend using a tube treated with anticoagulants such as
Citrate, EDTA, Oxalate, NaF, etc., except heparin, since the
blood-sampling tube containing such anticoagulants besides
heparin can drop the performance of the sensors and/or can
influence the analysis result.
 Make sure there are no small air bubbles trapped in the collected
sample. Small bubbles in the sample can affect the results.
 Samples containing clots and/or samples in which hemolysis is
present or suspected must not be used.
 Use whole blood samples for blood gas analysis should be
analyzed as soon as possible. If immediately analysis is not
possible, the sealed blood container must be placed in a bath
containing ice and water. Ice-water stored samples at 1 to 4°C
may give reliable results for up to 30 minutes.
