Allergic rhinitis is an inflammation of the mucous membranes of the nose caused by an allergic reaction to airborne particles. It is also known as hay fever or seasonal allergies. Allergic rhinitis affects an estimated 20-30% of people worldwide. The symptoms of allergic rhinitis include sneezing, itchy eyes, congestion, and a runny nose. Allergic rhinitis can be diagnosed through skin tests, blood tests, or a combination of the two.
Blood Test
A blood test for allergic rhinitis is a medical procedure that determines if a person has an allergy to specific substances. The test looks for antibodies in the blood that are a sign of an allergic reaction. If the test is positive, it means that the person has an allergic reaction to the substance tested, and the doctor can use this information to create a treatment plan.
Antibodies are proteins that are produced by the body in response to foreign substances, such as pollen or dust. When the body detects a foreign substance, it produces antibodies to fight it off. The presence of these antibodies in the blood is an indication of an allergic reaction.
How It Works
The blood test for allergic rhinitis is a simple procedure that involves taking a sample of blood from a vein in the arm. The sample is then sent to a lab for testing. The lab will look for antibodies that indicate an allergic reaction. If the test is positive, the doctor can then use this information to create a treatment plan.
