A full blood count FBC is test used to assess a patient's overall health. This test may also be used to detect blood disorders, or other conditions, that cause changes in the status of the blood cells.

A full blood count will include an evaluation of the red blood cells, white blood cells, hemoglobin, and platelets. This test will also assess the ratio of red blood cells to the total volume of blood in the sample. This ratio is referred to as the hematocrit Ht. A full blood count is also called a complete blood count CBC.

Because blood affects basically every system in the body, changes to the blood and abnormalities can affect health and well being quickly. If references ranges are required for paediatric patients please contact the laboratory for these.

Department of Haematology Notes Full blood counts are performed on automated equipment and provide haemoglobin concentration, red cell indices, white cell count with a differential count and platelet count. The presence of abnormal white cell and red cell morphology is flagged by the analysers. Blood films may be inspected to confirm and interpret abnormalities identified by the cell counter, or to look for certain specific haematological abnormalities.

Once the blood sample has been taken, the person taking the sample will ask you to press gauze or cotton wool against the injection site to minimise bleeding. They will cover the injection site with an adhesive dressing.

You may have minor bruising at the injection site for a day or two. Blood explained Approximately seven to eight per cent of your body weight is blood. Blood cells make up the other 40 per cent and include: red blood cells — known as erythrocytes. Every red blood cell contains haemoglobin, a protein that carries oxygen. Haemoglobin contains iron, which is important for carrying oxygen around the body white blood cells — known collectively as leukocytes.

These are cells of the immune system that fight infection. The different types of white blood cells include lymphocytes, eosinophils, monocytes, neutrophils and basophils.

Abnormalities in a full blood count The results of a full blood count are compared to charts that list the normal range of numbers and ratios for each type of blood cell. Abnormalities of the blood sample may include: red blood cells and haemoglobin — low levels anaemia may suggest not enough iron in the diet, blood loss or certain chronic diseases such as kidney disease. High levels polycythaemia may suggest polycythaemia vera, kidney disease, chronic lung disease or physiological changes due to living in areas of high altitude red blood cell to plasma ratio — a lower-than-normal ratio of red blood cells to plasma suggests the person may have anaemia.

The opposite finding suggests that the person may be dehydrated or has too many red cells polycythaemia white blood cells — low levels leucopenia may suggest the person has a viral infection, bone marrow disease or has been exposed to chemo- or radiotherapy. High levels leucocytosis may suggest bacterial infection, an inflammatory disease or bone marrow disease platelets — low levels thrombocytopenia may be the result of taking some medications, viral infection, bone marrow disorders, or an autoimmune disorder.

High levels thrombocythaemia may suggest the presence of a bone marrow disease or an inflammatory condition. Ask your doctor for further information about these tests. A blood smear can reveal: a range of diseases including red blood cell disorders such as sickle cell anaemia the presence of blood-borne parasites such as malaria a white blood cell disorder such as lymphoma or leukaemia.

Full blood count and accuracy The full blood count test is not foolproof and errors sometimes occur. Errors may include: failure of the equipment — for example, the blood clots in the vial incorrect labelling of the sample incorrect handling of the specimen — for example the sample is left in the sun and deteriorates contamination of the sample alcohol in the blood.
