Complete blood count or CBC or just “blood test” is an easy and very common test that tests blood for some disorders affecting your health.
What is Complete Blood Count (CBC)Test?
CBC determines whether there is any increase or decrease in the counting of your blood cells. Normal counting may vary depending on your age and your gender. The CBC report from the laboratory will tell you a general count for your age and gender.
CBC anemia can help detect many health problems from common infections to cancer.
Measuring the change in the level of your blood cells, your doctor can detect your overall health and disorders. This test measures three main types of blood cells –
Red blood cells deliver oxygen to your body and remove carbon dioxide. CBC measures two components of your red blood cells –
- Hemoglobin: Oxygen-carrying proteins
- Hematocrit: Percent of red blood cells in your blood
Decreased hemoglobin and hematocrit often is the symptom of anemia (anemia is caused by iron deficiency in the blood).
White blood cells help your body fight infection. CBC measures the number and type of white blood cells in your body. An abnormal increase or decrease in the number or type of white blood cells may be an indicator of infection, inflammation or cancer.
Platelets help control your blood clots and bleeding. When bleeding stops bleeding, it means that platelets are doing their job. Any change in the level of platelets can present you with the risk of excess bleeding and may be a sign of a serious medical condition.
Purpose of CBC
Your doctor may ask for a CBC test for regular checkups. Or if you have symptoms that can not be detected without testing, such as bleeding or injury due to which you do not know.
