4 Applicable Usage Methods
4.3 Tests Using a Plasma Filter (PF)
By using a PF, you can filter a plasma sample from a whole blood sample without using a centrifuge.
NOTE
The FDC NX600i cannot measure using a PF.
IMPORTANT:
Read the “Instructions for Use” of the PF before measurement.
IMPORTANT:
Be sure to read the PF card when changing to a new production lot of PFs.
CAUTION:
Do not tap the [START] button when the sample has already been filtered by the PF. If the [START]
button is tapped, the analyzer may malfunction.
Precautions for samples
NOTE
Use whole blood samples that have a hematocrit value (Hct) of 20 to 55%.
Up to about 350 μL of plasma (including 85 μL of dead volume) can be filtered.
The amount of filtered plasma decreases as the hematocrit value increases. In the case of
a hematocrit value of 55%, about 185 μL of plasma (including 85 μL of dead volume) can be
filtered.
The amount of filtered plasma depends on the hematocrit value and viscosity of the blood.
NOTE
Hemolyzed samples provide inaccurate results.
NOTE
If blood cells in a sample have precipitated, mix the sample, place it in a sample rack, and
then perform measurement immediately. Otherwise, the amount of filtered plasma may be
insufficient.
Precaution for blood collection tubes
IMPORTANT:
Use the blood collection tubes listed in Section 4.3.2.
