1. (Medicine) a centrifuge for separating blood cells from plasma
2. (Medicine) Also called: packed cell volume the ratio of the volume occupied by these cells, esp the red cells, to the total volume of blood, expressed as a percentage

The three-fold conversion of the haematocrit to derive a haemoglobin value is not affected by which factors?
Blood samples collected from fish were used to determine the haematological parameters (total red blood cell count, haemoglobin concentration, haematocrit, mean corpuscular volume, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration, total white blood cell count and differential leukocyte counts).
For patients in both groups, the decision to transfuse homologous packed RBCs was based on the patient's clinical assessment like pulse, blood pressure, urine output and/or a haematocrit (Hct) level (<20%).
As secondary outcomes, the difference in haemoglobin and haematocrit taken 24 to 2 hours before the intervention and 48 hours after the intervention was registered.
Abnormal blood tests were as follows: Haematocrit 37%; haemoglobin 11.9 g/dL; bicarbonate 21 mEq/L; urea 78 mg/dL (normal value 20-50 mg/dL); serum creatinine 2 mg /dL; uric acid 6.4 mg/dL; creatinine clearance 42 ml/min; proteinuria 0.2 g/day; urinary sodium excretion 188 mEq/day; urine pH: 6, urinary density 1015.
Of the factors contributing to whole blood viscosity, haematocrit, red cell aggregability, red cell rigidity, and plasma viscosity, haematocrit is thought to be the most important, being responsible for at least 70% of the contribution [17].

However, there were no significant differences between drip loss groups in RBC, hemoglobin, haematocrit, MCV, MCH, MCHC, platelets, neutrophils, eosinophils, lymphocytes and neutrophil:lymphocyte ratio.
The blood samples collected in bottles containing EDTA were gently mixed and drawn up in a micro haematocrit capillary tube to 3/4 of its length.
Body weight, blood haematocrit level, total sodium excretion and serum sodium and potassium concentrations were measured.
