Allergy Testing Basics
Allergies can be a difficult condition to manage, but testing can help you understand what triggers your symptoms and how to best manage them. Allergy tests can be done at a doctor's office or in a laboratory setting. Depending on the type of test, a doctor may use skin or blood tests to determine which allergens are causing your symptoms.
Skin Test
A skin test is one of the most common ways to diagnose allergies. It involves applying a small amount of an allergen to the skin and observing the reaction. If the skin reacts, it means you are allergic to that particular allergen.
Blood Test
If a skin test is not possible or if the results are inconclusive, a doctor may order a blood test. This type of test looks for specific antibodies in the blood that indicate an allergy to a particular allergen.
When to Ask for an Allergy Test
If you are experiencing any of the following symptoms, it may be time to ask your doctor for an allergy test:
• Persistent sneezing or coughing
• Wheezing or difficulty breathing
• Itchy or watery eyes
• Hives or rash
• Swelling of the face, lips, or tongue
• Nausea or abdominal pain
• Dizziness or lightheadedness
If you suspect you may have an allergy, it is important to talk to your doctor about getting tested. Allergies can be managed with the right diagnosis and treatment plan.
