The ALEX Allergy Explorer is a single blood test that measures your total IgE and specific IgE to a wide range of allergens at once, covering both whole allergen extracts and individual molecular components. From one blood sample it gives a broad map of what your immune system is sensitised to, which a GMC-registered doctor then interprets against your symptoms.

A single allergen test checks one suspected trigger. ALEX screens a wide range in one go, which is useful when you have several possible triggers, when triggers are unclear, or when you would rather see the whole picture than test one at a time. It also reports molecular components, not just whole extracts, which adds a level of detail a basic test does not.

Whole allergens are made of several proteins, or components. Component-resolved testing shows which specific component you react to, not just the source. This helps a doctor tell a likely genuine allergy from a harmless cross-reaction, for example separating a true nut allergy from a pollen-related cross-reactivity that causes only mild mouth itching. That detail can change the advice you are given and informs decisions such as whether to consider immunotherapy or specialist referral. It is interpreted by a doctor and does not replace clinical judgement.

ALEX suits people with symptoms that have several possible triggers, unclear or confusing food reactions, suspected pollen-food cross-reactivity, or anyone who would prefer a broad one-sample screen rather than testing allergens one at a time. It is also helpful background before a conversation about immunotherapy. If you already have one clear suspected trigger, a single allergen test may be all you need, and the doctor will advise.

Not on its own. Like any IgE test, ALEX shows sensitisation, meaning your immune system recognises an allergen or component. Whether that causes your symptoms is judged by a doctor alongside your history, and a result is never read as a simple yes or no. This is exactly why ALEX is offered with doctor interpretation rather than as a raw report.

It is a single blood sample taken in clinic, usually 15 to 30 minutes, with no fasting needed. The sample is processed by an accredited UK laboratory. Because ALEX is a broad panel it can take a little longer than a single test, and the expected turnaround is confirmed when you book. Your result is reviewed by a doctor and sent securely to your email, password-protected.

No. You can book online, in person at the clinic, or add the test during a GP consultation at KONCEPT®. A GMC-registered doctor reviews each request and confirms whether ALEX or a more targeted test is the better fit before your appointment.

The ALEX Allergy Explorer is 379 pounds, which is 418 pounds all-in with the single 39 pound administration fee that covers your whole visit, charged once per visit and never per test. If a GP review is recommended afterwards, that is a separate booking: your NHS GP at no NHS charge, or a KONCEPT GP consultation at 149 pounds.

NHS allergy care, through your GP and specialist allergy clinics, remains the right route for many people, particularly anyone who has had a severe reaction. KONCEPT® offers ALEX directly, without referral, with a doctor to interpret the broad result against your history. With your written consent we share a clinical summary with your NHS GP, and we refer on to specialist allergy services where that is the right next step.
