Basophils are a type of white blood cell that helps the body fight allergic reactions and parasitic infections. They are produced in the bone marrow and then travel to the bloodstream, where they can quickly travel to the site of an allergic reaction or infection. Basophils release histamines and other chemicals that help to fight the allergic reaction or infection.
A complete blood count (CBC) is a blood test that measures the number of different types of blood cells, including basophils. The normal range for basophils in a CBC is 0.5% to 1% of the total white blood cell count.
A high basophil count, called basophilia, can be a sign of a number of conditions, including:
A low basophil count, called basopenia, can be a sign of a number of conditions, including:
There is no specific treatment to improve basophil levels. Treatment is focused on the underlying condition that is causing the abnormal basophil count. For example, if the abnormal basophil count is caused by an allergic reaction, antihistamines may be prescribed. If the abnormal basophil count is caused by leukemia, chemotherapy may be prescribed.
Here are some lifestyle changes that may help to improve basophil levels:
If you are concerned about your basophil levels, you should talk to your doctor. Your doctor may want to do further tests to rule out any underlying medical conditions.
