4681 Establishing the haematocrit

Code and name of test:

4681 – Establishing the haematocrit

The haematocrit shows, in percentages, the quantity of erythrocytes in the analysed blood. It is established by centrifuging the blood rendered incoagulable and dividing the height of the erythrocyte count to the total blood count. The only anticoagulant used is the dry one (mixture of oxalates, heparin or EDTA), so that the quantity of plasma is not modified. It is established in venous blood and in capillary blood (microhematocrit). The centrifuging is performed with a certain number of rotations (3,000 rpm), for a certain period (30 min).
