This FBC (Full Blood Count) blood test provides important information about the type, number and appearance of cells in the blood, especially red blood cells (vital for carrying oxygen around the body), white blood cells (key to the body's immune system), and clotting cells (important for controlling and stopping bleeding). It is a broad based test covering 16 measures.
The full blood count is a comprehensive analysis of the red and white blood cells in your blood. Haemoglobin carries oxygen and gives the red blood cell its red colour. This test measures the amount of haemoglobin in the blood and is a good measure of the bloods ability to carry oxygen around the body.
A high haemoglobin result can mean increased red cell production to compensate for chronically low oxygen levels in the blood caused by lung disease or living at altitude. While it can also indicate blood doping, other causes can include dehydration, smoking and bone marrow disorders.
MCV (mean corpuscular volume) reflects the size of your red blood cells. A high result may indicate a vitamin deficiency of folate or vitamin B12 and is often seen in excessive alcohol consumption associated with liver inflammation. A low result indicates anaemia, often caused by iron deficiency.
MCH (mean corpuscular haemoglobin) is the average amount of haemoglobin contained in your red blood cells. Together with MCV and MCHC, MCH results can help in the diagnosis of different types of anaemia.
MCHC (mean corpuscular haemoglobin concentration) is the average concentration of haemoglobin in your red blood cells. A high level can indicate the presence of spherocytes (a type of red bood cell with too much haemoglobin) or a deficiency of folic acid or vitamin B12 in the diet. A low level can indicate chronic blood loss or iron deficiency.
RDW (red cell distribution width) shows whether the cells are all the same size or different sizes or shapes. Normally cells are fairly uniform. A raised RDW result (indicating greater variaton in cell size and shape than is normally seen) can be caused by deficiency in iron, vitamin B12 or folic acid.
A low haemoglobin result indicates anaemia which can have many causes including pregnancy, blood loss, liver damage, iron deficiency and much more. A low haemoglobin level should be investigated in line with other symptoms and results.
HCT (haemocrit) measures the amount of space (volume) red blood cells take up in the blood. Raised levels can result from pregnancy, living at altitude, dehydration as well as low availability of oxygen through chronic lung disease and even sleep apnoea. Low levels indicate anaemia.
RBC (red blood count) analyses the number of red cells in the blood. Red blood cells carry oxygen from the lungs to the rest of the body. They also carry carbon dioxide back to the lungs so that it can be exhaled. A high count (thicker blood) means there is a chance that the red blood cells will clump together and block tiny blood vessels. This also makes it difficult for your red blood cells to carry oxygen. A low count (anaemia) means that your body may not be getting the oxygen it needs and can be caused by nutritional deficiency (lack of iron, folic acid, vitamin B12), over-hydration as well as bleeding and bone marrow disorders.
All blood cells are made in the bone marrow, the centre of large bones. Some medications or diseases can damage the bone marrow, which in turn can reduce the numbers of different types of red or white blood cells.
This FBC (Full Blood Count) blood test provides important information about the type, number and appearance of cells in the blood, especially red blood cells (vital for carrying oxygen around the body), white blood cells (key to the body’s immune system), and clotting cells (important for controlling and stopping bleeding). This is an important test for the diagnoses of anaemia which is caused by insufficient red blood cells or haemoglobin as assessing immune function.
This FBC test (Full Blood Count) is for individuals who wish to establish the health of their blood. It is an important blood test for people who have symptoms of amaenia or who suspect a viral or bacterial infection.
