Skin Allergy Testing London & Skin Prick Test London

Fast and Accurate Allergy Diagnosis with Same-Day Results

At the London Allergy and Immunology Centre, we provide skin allergy testing in London using proven skin prick testing (SPT). This test helps identify which allergens trigger your symptoms. It is quick, safe, and reliable.

Skin prick testing suits adults, children, and infants. In most cases, results are ready within 15–20 minutes. As a result, your consultant can explain the findings and discuss next steps during the same visit. Most appointments last around one hour.


What Is Skin Prick Testing?

Skin prick testing is a first test for immediate allergic reactions. These reactions involve IgE antibodies and appear soon after exposure.

 

Skin Prick Allergy Test London
Our skin prick test is performed by experienced medical staff with review by consultants, who interpret your results in the context of your full clinical history. Testing is available for adults, children, and even infants, and takes place during your appointment.
(Please note that antihistamine tablets should be avoided for two days prior to the test)

During the test, trained medical staff place small amounts of allergens on the skin. After that, a consultant reviews the results alongside your symptoms and medical history. This step ensures accurate interpretation.

Doctors commonly use skin prick testing to assess:

– Hay fever and seasonal allergies
– Ongoing nasal allergy symptoms
– Food allergy
– Eye allergy symptoms
– House dust mite allergy
– Pet allergy
– Mould allergy

Because results appear quickly, skin prick testing supports same-day diagnosis and treatment planning.

Important: Please stop antihistamine tablets 48 hours before testing, unless your consultant advises otherwise.

Because the test produces rapid results, it supports same-day diagnosis and treatment planning.

How Skin Prick Testing Works

First, the clinician places a tiny drop of allergen extract on the skin. This is usually done on the forearm or back. Next, a sterile lancet lightly touches the skin surface.

– The test does not involve injections
– Controls are included for accuracy
– A small raised bump may appear if sensitisation is present


Testing with Fresh or Cooked Foods

When food allergy is suspected, we may perform prick-to-prick testing or modified allergy testing. In this case, fresh or cooked foods are used instead of standard extracts.

You may bring small food samples in sealed containers.


Is Skin Prick Testing Safe?

Yes. Skin prick testing is very safe when trained professionals perform it. Research confirms its use even in infants from birth.

– Reactions stay local to the skin
– Mild redness or itching may occur
– Serious reactions are extremely rare

Because of this, the test is widely used in paediatric allergy care. Our team also ensures a calm and child-friendly experience.


Same-Day Results and Clear Advice

You do not need to wait days for results. Instead, your consultant explains the findings during your visit.

You may receive advice on:

– Avoiding confirmed allergens
– Reducing exposure at home
– Whether further testing is helpful
– Long-term allergy management

Skin Prick Test vs IgE Blood Test

Both tests help diagnose allergy. However, they measure different responses.

Skin prick testing shows the skin’s immediate reaction. Antihistamines and some skin conditions can affect results.
IgE blood testing measures antibodies in the blood. It is not affected by antihistamines.

For this reason, many patients benefit from using both tests together.

Frequently Asked Questions

How long does skin prick testing take?

The test itself takes about 15 minutes.
The full appointment, including consultation and result discussion, lasts around one hour.


Can I take antihistamines before the test?

No. Please stop taking antihistamines at least 48 hours before testing, unless your consultant advises otherwise. Antihistamines can reduce skin reactions and affect results.


Is skin prick testing safe for babies?

Yes. Skin prick testing is safe and can be performed from birth when clinically appropriate. It is widely used in paediatric allergy care.


Is the test painful?

No. The test is not painful. Most people describe the sensation as tickly or mildly itchy.


Can I have skin prick testing if I am pregnant?

Yes. Skin prick testing can be performed during pregnancy. Your consultant will explain the test in detail and answer any questions you may have. After you give informed consent, the test can be arranged safely.

Alternatively, your consultant may recommend a blood allergy test. This option does not involve the skin but takes a little longer for results to return.


Can skin prick testing be done for a newborn baby?

Yes. Skin prick testing can be performed safely in newborn babies when clinically indicated.

Your consultant will first review your baby’s symptoms and medical history. They will then explain the options and advise whether skin prick testing or a blood allergy test is more suitable. With appropriate medical supervision, skin prick testing is safe and well tolerated even in very young infants.
