Preparing for an Allergy Test: What You Should Know
Allergies are an increasing concern in the UK, with millions experiencing reactions to various substances. According to Allergy UK, around one in four people in the UK suffers from some form of allergy, impacting their quality of life.
An allergy test can help accurately identify specific triggers, guiding effective treatment. Below, we outline the different types of allergy tests available, along with essential preparation steps to take before your appointment.
How Allergies Impact Your Life
Allergies are conditions in which the immune system overreacts to usually harmless substances, such as pollen, dust mites, and animal dander. Common symptoms include:
- Nasal congestion and runny nose
- Frequent sneezing
- Itchy and watery eyes
- Breathing difficulties (in the case of allergic asthma)
- Skin rashes and hives
These symptoms can interfere with daily activities, affecting work, studies, sleep, and even social interactions.
Allergies that are not adequately treated may lead to more serious complications, such as respiratory infections or asthma attacks. Therefore, the importance of accurate diagnosis and appropriate treatment cannot be underestimated.
Types of Allergy Tests Available
Depending on your symptoms, a doctor may use one or more of the following tests to identify triggers:
- Skin Allergy Test: Commonly used for reactions to particles like pollen or animal dander. Tiny allergen samples are applied to the skin, which is then pricked. A red bump indicates sensitivity. Results show in about 15 minutes.
- Intradermal Test: For cases needing further analysis after a skin prick test, small amounts of allergens are injected under the skin. It’s useful for insect or medication allergies.
- Patch Test: For suspected contact allergies, small patches with allergens are applied to the skin for 48 hours, testing for reactions like rashes.
- Challenge Test: Often used for food or medication allergies, this involves controlled allergen exposure under medical supervision.
- Blood Test: Measures IgE antibodies to allergens, useful if skin testing isn’t feasible.
Preparing for Your Allergy Test: What to Avoid
For accurate test results, certain guidelines should be followed:
- Antihistamines: Stop taking antihistamines (such as Allevia) 3-7 days before the test, per your doctor’s advice, as they can affect results.
- Specific Antacids and Beta-Blockers: Some antacids with antihistamines and beta-blockers should be avoided. Consult your doctor.
- Tricyclic Antidepressants: Medications like amitriptyline may need to be paused to avoid interference.
- Fragrances and Cosmetics: Avoid perfumes, hairsprays, and strong lotions to prevent skin irritation.
What You Can Do Before an Allergy Test
- Stay Hydrated: Drinking water maintains health and can help during the test.
- Follow Usual Diet: Continue your normal diet unless otherwise advised.
- Steroid Nasal Sprays: Usually permitted, but confirm with your doctor.
What to Expect from Allergy Test Results
The results of an allergy test are generally available within a few hours or days, depending on the type of test conducted. For skin prick tests, results can be observed immediately, with reactions appearing as small red bumps.
After the test, your doctor will explain the results and discuss treatment options. Mild reactions, such as redness or swelling, are common and typically disappear within a few hours.
