Notes
Result of "Haematocrit" assay, performed on blood sample, obtained from UK Biobank assessment centre visit. Haematocrit Percentage is the relative volume of packed erythrocytes to whole blood, computed by the formula: (red blood cells x mean corpuscular volume) / 10.
Analyser operating range was 0 to 99.9%
Typical reference range is 35.4 to 47.2%
