The full blood examination (FBE), also known as the Full Blood Count (FBC), provides important information about the numbers and correct development of cells in the blood: red blood cells that carry oxygen, white blood cells that fight infection and platelets that help blood to clot.
Abnormalities in any of these can tell us a lot about a range of important conditions including some nutritional factors, medications and, occasionally, exposure to toxic substances. Abnormalities in this blood test can be caused by anaemia, infections, some blood cancers such as leukaemias and some inherited conditions.
What are each cells responsible for in the human body?
Red Blood Cells: Are responsible for carrying oxygen around the body. A high count can increase the chance of heart attack or stroke, whilst a low count can mean your body isn’t getting the oxygen it requires.
White Blood Cells: Are responsible for fighting an infection. A high count can indicate recent infection and even stress, whilst a low count can result from vitamin deficiencies, liver disease and immune diseases.
Platelet Count: Are responsible for blood clotting and healing. A high count can indicate a risk of thrombosis, whilst a low count can lead to easy bruising.
Haemoglobin: Is an important marker of your blood’s ability to carry oxygen throughout your body. Often elevated haemoglobin can be an indicator of lung disease, whilst a low result indicates anaemia.
Haematocrit: Is a measure of the percentage of red blood cells in the total blood volume. Elevated haematocrit can increase the risk of heart attack or stroke.
