Allergy Testing: What to Expect and How It Helps

Skin allergy on a person's arm

Allergies affect millions of people in the UK, often without them realising the exact cause of their symptoms. If you suffer from sneezing fits, itchy eyes, unexplained rashes, or even digestive issues, an allergy test could give you the clarity you need. In this guide, we’ll explain how to get an allergy test, what happens during the process, and how the results can help you manage your health more effectively.

Why Consider an Allergy Test?

Allergies don’t just cause mild discomfort — they can impact your daily life, from disrupted sleep to reduced productivity. In some cases, untreated allergies may even worsen or lead to more serious complications such as asthma. Getting tested allows you to:

  • Identify specific triggers (pollen, dust, food, or pet dander).
  • Take control of your environment and lifestyle.
  • Receive the right treatment, whether it’s avoidance advice, medication, or specialist referral.

How to Get an Allergy Test

You have several options when it comes to allergy testing:

  • NHS referral – often requires GP assessment first, and waiting times can be long.
  • Private allergy test clinic – faster appointments, wider choice of tests, and more time with your doctor.

At Private Medical Clinic, we provide same-day appointments for allergy testing and tailored advice, making it easier for you to start your treatment plan without delays.

Where Can You Get Allergy Tested?

Allergy testing is widely available across the UK. You can:

  • Book through your NHS GP (though availability may be limited).
  • Choose a private allergy test clinic (ideal for faster results and more in-depth consultations).
  • Visit a hospital or specialist centre if your case is complex.

We offer allergy testing in Birmingham, Sutton Coldfield, London, Oxford, Newcastle, and other locations — making it simple to access care wherever you are.

(You may also find our blood test services and asthma assessments useful if your symptoms overlap.)

What Types of Allergy Tests Are Available?

Skin Prick Test

A small drop of allergen is placed on the skin, then gently pricked. If you’re allergic, a red bump appears. This test is quick and gives results within 15–20 minutes.

Blood Test (Specific IgE or ImmunoCAP)

A blood sample is taken to measure your immune system’s response to allergens. This is often the go-to for people who can’t have skin tests due to skin conditions or medications.

Patch Testing

Mainly used for skin allergies (eczema or contact dermatitis). Small patches with allergens are applied to your skin for 48 hours.

Allergy Test Cost

The cost varies depending on the type of test and whether you go private.

  • Skin prick tests usually start from £80–£120.
  • Allergy blood tests range between £100–£250 depending on how many allergens are screened.
  • Comprehensive packages may include consultation, test, and results discussion.

At Private Medical Clinic, we offer transparent pricing with no hidden fees. You’ll always know your allergy test cost upfront before booking.

Allergy Blood Test Results Explained

Once your results are back, your doctor will explain what they mean in plain English.

  • Positive result: You have higher antibodies (IgE) to a particular allergen.
  • Negative result: No reaction detected, meaning the allergen is unlikely to be the cause.
  • Borderline result: Sometimes further testing or monitoring is needed.

We don’t just hand you a printout — we take the time to explain how your allergy blood test results fit into your symptoms, lifestyle, and next steps for treatment.

Benefits of Visiting an Allergy Test Clinic

By choosing a dedicated clinic, you’ll benefit from:

  • Quick access – no long NHS waiting lists.
  • Tailored advice – personalised recommendations based on your results.
  • Comprehensive care – from diagnosis to ongoing treatment, if needed.

You’ll also have access to related services such as asthma reviews, skin checks, and private GP consultations if you need broader support.

FAQs About Allergy Test

How long does an allergy test take?

Skin prick tests usually take around 20–30 minutes, while blood tests can be done in minutes but may take a few days for results.

Do I need to stop taking antihistamines before testing?

Yes, antihistamines can affect results, especially for skin prick tests. Your doctor will advise you on how long to stop beforehand.

Can children have allergy tests?

Absolutely. Children often benefit from early testing to identify triggers that affect their development and wellbeing.

Will my results show all my allergies?

Tests can screen for the most common allergens, but no test covers every possible trigger. Your doctor will help decide which tests are most relevant for you.

Are private allergy tests worth it?

If you want fast access, detailed explanations, and treatment options without waiting months for a referral, private allergy tests are highly worthwhile.
