Red blood cells: red blood cells are vital; they carry oxygen around the body and help to remove waste products from the body. The full blood count measures the number of red blood cells in the body. The red blood cell count measures the number of red blood cells within the volume of blood; if the number is XXXXX high or low this can signify a medical health problem. Red blood cells are red because they contain haemoglobin, which has a deep red colour.
White blood cells: white blood cells are a vital part of the body’s immune system. White blood cells are responsible for fighting off infections and helping to protect the body against harmful bacteria. There are many different types of white blood cells, including lymphocytes, neutrophils, monocytes, basophils and eosinophils. The full blood count can measure the total number of white blood cells in the blood (this is known as the white blood cell count); a white blood cell differential test assesses the different types of white blood cells. White blood cells are colourless because they do not contain haemoglobin.
Platelets: platelets are also known as clotting cells, as they are responsible for clotting. Platelets stick together to stem bleeding; if there are not enough platelets, an individual may experience excessive bleeding, while a high platelet count can contribute to the formation of blood clots. The full blood count contains a platelet count, which can help doctors to diagnose problems with clotting.
Haemoglobin: haemoglobin is a vital component of the blood; it carries the oxygen around the body in the bloodstream. Haemoglobin also gives red blood cells their colour. The full blood count measures the amount of haemoglobin in a volume of blood; this can help doctors to assess the body’s ability to transport oxygen around the body.
Haematocrit: also known as HCT, this is a test which measures the amount of space taken up by the red blood cells in a set volume of blood; the result can either be recorded as a percentage or a proportion (recorded as 0-1).
Mean corpuscular volume: the mean corpuscular volume is a measurement of the average size of the red blood cells; if the cells are too large or too small, this can contribute to problems.
No, bacteria/viruses would not show up.
