Samples with
extremely high hematocrit levels
Uncap
the tube
Pipette 250 μL to 270 μL of whole blood
into the centrifuge tube. Insufficient
sample volume may result in incorrect
measurement results. Excessive volume
may cause blood to stain the cover.
●
Heparin is contained as an anticoagulant.
Close the cap tightly after setting a
sample, and invert it and use the sample
after removing the cap.
Remove air bubbles or skin on the
surface of the sample, if any. Otherwise
they may cause incorrect measurement
results.
Wipe out the sample attached to the
outside of centrifuge tube before placing
it to the centrifuge, otherwise it may
cause spattering the sample.
●
Samples with extremely high hematocrit
levels may yield incorrect measurement
results.
●
Heparin
When it takes time before blood samples
collected are brought into the centrifuge,
the samples may begin to coagulate.
The samples, which show heavy
coagulation or deposition of fibrin, may
not be subjected to measurement.
A syringe containing heparin can be
used to prevent coagulation when it
takes time before the samples are
brought into the centrifuge, although the
machinecontains heparin.
