stored refrigerated (2-8°C). Prepare the sample for testing as
follows:
1. Remove sample tube from the refrigerator and bring it to
room temperature (15-30°C).
2. Mix the sample well (i.e. by a mechanical rotator or by
inverting by hand).
3. Take out a microcuvette from the container and
immediately close the lid.
Please note Section 4.1.1 “Notes on using the microcuvette”.
4. Pipette a sufficient drop of blood on a non-absorbent
material (i.e. plastic film).
5. Hold the center
of the cuvette in the middle of the drop of
blood and wait until the cuvette is filled completely (see
Illustration 15). DO NOT fill from the side as this could
create air bubbles in the cuvette optic window and result
in an erroneous result.
Illustration 15: Taking a sample of venous or arterial blood.
Ensure that the cuvette cavity is completely filled and free of air
bubbles. DO NOT try and top-off cuvette if not filled completely.
Repeat the process with a new drop of blood and a new cuvette.
6. In order to avoid contamination of the cuvette holder,
remove excess blood from the outside of the cuvette by
