A full blood count (also known as a Complete Blood Count, CBC or FBC) looks at three main components that make up your blood: Red Blood Cells, White Blood Cells, and Platelets. The full blood count is one of the most commonly requested tests as it provides a general snapshot of your health and can screen for a variety of disorders, such as anaemia and infection, inflammation nutritional status, and bleeding.
Unlike other markers, such as Cholesterol, your full blood count test results are not normally affected by your lifestyle and are usually a result of an underlying health condition, deficiency (such as vitamin B12 or folate deficiency, or iron deficiency), or increased alcohol intake. By understanding your full blood count, it can help address these potential underlying health conditions.
A full blood count blood test usually looks at the following biomarkers:
The full blood count is commonly requested by your GP and Doctor as it provides a great insight into monitoring as well as screening and helping diagnose a range of health conditions.
A full blood count is often very useful in:
Your red blood cell count (RBC count) is the actual number of red blood cells per volume of blood. Red blood cells are important in the transportation of oxygen around the body. Red blood cells can be decreased in anaemia or an increase in red blood cells can be caused by diarrhoea, dehydration, and burns. The essential component in red blood cells is Haemoglobin, as this is the protein that transports oxygen around the body. Your results will show everything from the size to the volume of Haemoglobin
Your white blood cell count (WBC count) is the total number of white blood cells per volume of blood. White blood cells are part of your immune system and are important in fighting infections. An increase in white blood cell count may be a sign of an infection or inflammation. A decrease in white blood cell count can be caused by some medications or an autoimmune condition. To help us understand this in more detail, we can look at the different types of White Blood Cells in our body, there are five of them, each with its own function: Neutrophils, lymphocytes, monocytes, eosinophils, and basophils
Your platelets are involved in blood clotting, such as helping to form a clot when you cut yourself. Too few platelets may cause problems in the blood clotting when it needs to, such as to prevent excessive blood loss. Too many can increase the risk of blood clotting in the blood vessels and cause organ damage
