A complete blood count(CBC) is a blood test that is used to evaluate your overall health and also detect a wide range of disorders, such as: anemia, infection and leukemia.
A complete blood count test measures several features of the blood, including:
- Red blood cells. (They carry oxygen).
- White blood cells. (They fight infection).
- Hemoglobin. (The oxygen-carrying protein in red blood cells).
- Hematocrit, the proportion of red blood cells to the fluid component, or plasma, in your blood
- Platelets. (They help with blood clotting).
A complete blood count test can:
- Detect anemia, infection or leukemia,
- See if you have another health issue,
- To explain symptoms such as: fever,weakness, bruising, or feeling tired,
- Keep an eye on a blood condition that you might already have,
- See how treatments like chemotherapy are affecting your blood.
CBC is very important for several good reasons, including the following:
- White blood cell count (WBC or leukocyte count).
- WBC differential count.
- Red blood cell count (RBC or erythrocyte count).
- Hematocrit (Hct).
- Hemoglobin (Hbg).
- Mean corpuscular volume (MCV).
- Mean corpuscular hemoglobin (MCH).
- Mean corpuscular hemoglobin concentration (MCHC).
- Red cell distribution width (RDW).
- Platelet count.
- Mean Platelet Volume (MPV).
Preparations for CBC
Before you undergo a CBC test you must prepare. We suggest you to:
- Make sure you wear a short-sleeved shirt or a shirt with sleeves that you can easily rollup.
- Eat and drink normally before a CBC.
- However, it depends on your condition as well, so before you take the test you will be in contact with the doctors and they will tell you how to prepare more specifically.
