first as an anticoagulant and second to be sure the hematocrite is lower than 35%.

Now days the labs use EDTA as anticoagulant (sample stability is much better 24 hours in stead of 4 hours) but still need to dilute the blood sample regarding the hemathocrite value. This regarding ICSH recommendations for measurement of erythrocyte sedimentation rate.
