Haemoglobin
Learn more
Haemoglobin is a protein in red blood cells which carries oxygen around the body and gives the blood its red colour. This test measures the amount of haemoglobin in the blood and is a good measure of the blood's ability to carry oxygen around the body.
Haematocrit
Learn more
HCT (haematocrit) measures the amount of space (volume) within the blood that is taken up by red blood cells.
Red cell count
Learn more
Red Blood Cell (RBC) Count analyses the number of red blood cells in the blood. Red blood cells carry oxygen from the lungs to the rest of the body, where it can be used to fuel energy processes such as movement and respiration. They also carry carbon dioxide produced from cells back to the lungs so that it can be exhaled.
MCV
Learn more
MCV (mean corpuscular volume) reflects the average size of your red blood cells. This is important to measure, as it can indicate how much oxygen your cells are likely to be transporting around the body.
MCH

MCH (mean corpuscular haemoglobin) measures the average amount of haemoglobin contained in one of your red blood cells.
