A complete blood count (CBC) for allergic rhinitis is a type of blood test that measures the number and types of cells in your blood. This test can help diagnose and monitor allergies, such as allergic rhinitis. Allergic rhinitis is an inflammation of the nasal airways caused by an allergic reaction to airborne particles, such as pollen or dust mites.
Symptoms of Allergic Rhinitis
Allergic rhinitis can cause a range of symptoms, including sneezing, runny nose, nasal congestion, itchy eyes, and postnasal drip.
Why Do You Need a CBC for Allergic Rhinitis?
A CBC for allergic rhinitis is typically used to diagnose or monitor allergies. The test helps your doctor understand how the number of different cells in your blood is affected by an allergic reaction. For example, if you have high levels of eosinophils, a type of white blood cell, this indicates that there is an allergen present in your body.
How Is a CBC for Allergic Rhinitis Performed?
A CBC for allergic rhinitis is performed by drawing a sample of your blood. The sample is then sent to a laboratory for analysis. The lab will count and measure the number of different types of cells in the sample.
What Do the Results Mean?
The results of a CBC for allergic rhinitis can help your doctor diagnose or monitor allergies. If the results show higher than normal levels of eosinophils, it is likely that you have an allergic reaction to an airborne particle. If the results show high levels of other types of blood cells, such as neutrophils or basophils, this could indicate other types of allergies or infections.
