The ALEX³ screens 300 allergens — 82 whole allergens and 218 molecular components — from a single finger prick blood sample taken at home.
 
Your kit arrives by Royal Mail Special Delivery next working day. Take the sample at home in 15–20 minutes, return it in the pre-paid packaging, and receive your full results report by email from The London Allergy Clinic within 2 working days.
 
You can continue taking antihistamines right up to the point of taking the sample.
 
Suitable for adults, children and babies from 18 months. For children under 18 months, please book a consultation first.
 
£350 includes the kit, free next-day delivery, pre-paid return postage, UKAS-accredited laboratory analysis and your full results report.
 
If you would like a Consultant Allergist to interpret your results, a consultation can be booked separately (£350) — before or after your test.

Step 1 — Dispatch. Your kit is sent by Royal Mail Special Delivery, guaranteed next working day by 1pm. Orders placed on weekends or bank holidays are dispatched the next working day.

Step 2 — Take your sample. Follow the instructions included in the kit. The whole process takes 15–20 minutes and can be done at home. You can eat, drink and take all regular medications — including antihistamines — as normal.

Step 3 — Post it back. Place the sealed sample tube in the pre-paid return packaging and post it. Do not post on Friday or Saturday — the laboratory is closed over the weekend.

Step 4 — Receive your results. Your full report is emailed to you by The London Allergy Clinic within 2 working days of the laboratory receiving your sample.
Post your sample on the same day you take it. If same-day posting is not possible, the sample can be stored in the fridge overnight.

Do not post on Friday or Saturday (lab closed weekends — delays affect results).

Do not take the test within 4 weeks of an allergic reaction — there is a risk of false negative results.

For children under 18, the test must be supervised by a parent or guardian.

If the blood sample is insufficient, a £35 postage and packaging fee applies to send a replacement kit.
