Full Blood Count
A full blood count (FBC) is a common diagnostic test that is used to assess the overall health of the blood and identify any potential abnormalities or conditions. It involves analyzing a sample of blood to measure various components of the blood, including red blood cells, white blood cells, and platelets.
Uses Of Full Blood Count.
There are a few different reasons why a healthcare provider may order an FBC.
- One common reason is to check for anemia, a condition in which there are not enough red blood cells or hemoglobin (the protein in red blood cells that carries oxygen) in the blood. Anemia can cause symptoms such as fatigue, shortness of breath, and pale skin.
- An FBC can also be used to assess the function of the immune system and to diagnose conditions such as infections, autoimmune disorders, and blood cancers.
- It can also be used to monitor the effectiveness of treatment for these conditions.
Sampling For Full Blood Count
To collect a sample for an FBC, a healthcare provider will typically draw a small amount of blood from a vein, usually in the arm. The blood is then sent to a laboratory for analysis.
The laboratory will use a machine called a haematology analyser to measure various components of the blood, including the number of red blood cells, white blood cells, and platelets. The results of the FBC can help healthcare providers to diagnose and treat a range of conditions.
It is important to follow the healthcare provider’s instructions for preparing for the blood draw, as certain medications or activities may interfere with the test.
Overall, an FBC is a useful diagnostic tool that can help healthcare providers to assess the overall health of the blood and identify any potential abnormalities or conditions. By following the healthcare provider’s instructions carefully and understanding the purpose of the test, patients can help to ensure accurate and reliable results.
