4 Applicable Usage Methods
4. Load the sample.
(1) Place the specified amount of whole blood
sample in a blood collection tube.
NOTE
The PF has about 3 mL of dead vol-
ume (that will be absorbed into the
filter). If the sample volume is low,
the filtered sample volume will be
too low for measurement. Further-
more, sample that was aspirated
into the PF filter cannot be reused.
NOTE
If the sample volume is too high,
the sample may overflow from the
blood collection tube when the PF is
loaded. There must be empty space
in the tube. (Refer to Section 4.3.2.)
(2) Mix the whole blood sample in the blood
collection tube by turning it over five or six
times.
NOTE
Make sure that bubbles do not form.
(3) Remove the cap from the blood collection
tube, and then put it on the PF sample rack.
(4) Insert a PF into the blood collection tube.
Make sure the PF does not rise from the
sample rack.
5. Register the measurement information.
IMPORTANT:
Tests using a PF measure filtered plasma, so al-
ways configure the sample type to [Plasma/Serum].
