TEST RESTRICTIONS

TEST LIMITATIONS - THIS IS NOT A FOOD INTOLERANCE TEST.

Allergy testing (this test) evaluates immune-mediated reactions, specifically IgE-driven hypersensitivity. When an allergen enters the body, the immune system produces allergen-specific IgE antibodies, which bind to mast cells and basophils. On re-exposure, these cells release histamine and other mediators, causing rapid symptoms such as hives, swelling, wheeze, or anaphylaxis. An allergy screen (this test) therefore measures IgE responses only, helping identify substances that trigger true immunological allergic reactions.

Intolerances, by contrast, do not involve IgE or the immune system. They typically result from enzyme deficiencies, chemical sensitivities, or difficulty digesting or metabolising certain substances. Symptoms are usually delayed, dose-dependent, and non-life-threatening, for example, bloating from lactose intolerance or headaches triggered by food additives. Because these processes are non-immune in nature, they cannot be detected by an IgE allergy screen.

This test identifies allergies only and will not provide information about intolerances.

ULTIMATE ALLERGY SCREENING (ALEX 3.0) BLOOD TEST - OVERVIEW

This is truly the best way to start your allergy diagnosis and treatment journey.

For people with multiple allergen sensitivities or those experiencing unclear clinical symptoms, the traditional method of determining individual allergens can be both costly and time-consuming. In such situations, a comprehensive allergen screening provides a clear understanding of the patient's sensitisation profile and serves as a potent tool for accurate diagnosis and preventing exposure to allergens.

The identification of allergen-specific IgE antibodies in the blood serum plays a critical role in diagnosing type 1 allergies and this test allows simultaneous testing of 295 common allergens, giving you a clear baseline for further exploration of specific allergens. Allergy testing is often a "stab in the dark" and this test allows you to avoid that entirely.

  1. TURNAROUND TIME

    We are extremely fast, with some results available within hours and others within a working day or less, from the time your sample is in our lab. However, this is not a guarantee and should not be taken as such. This is the guideline turnaround time that can be shorter or longer.


    THIS IS NOT A GUARANTEED TURNAROUND TIME.


    We are extremely proud of our very short turnaround times and a very efficient laboratory processes, you will start receiving results as soon as they are available and have completed clinical validation.


    Whilst we accommodate the shortest of time scales, with some results available within hours, for this particular test the usual turnaround time is: 5 working days.

  1. WILL I HAVE A GENERAL EXPLANATION OF MY RESULTS?

    The report for the ALEX 3.0 screen marks each of the allergens with a score. This is sufficient to understand your general level of exposure, so it does not come with any additional explanation as it's not needed.


    Allergy testing is a complex and difficult area, so it is important to act on any allergies indicated and speak to an allergy specialist and follow up with a skin prick test.

  1. CAN I SEE A GP TO DISCUSS MY RESULTS?

    Yes, usually the same or next day.


    One Day Tests has a fantastic clinical team of consultants and GPs. Once you have your results you can book an online video consultation to discuss your results.


    Our clinical team consists of practicing NHS and private GPs, who work closely with our laboratory and can tell you what your blood test results mean for you. Having an integrated laboratory and GP services makes your health journey seamless and extremely efficient.


    This service is not included in the price of the test, it is charged separately, should you wish to book it.

DOCTOR'S COMMENTS

Hi, I am Dr. Adam Staten and here's my view on this test as a GP and Clinical Director at One Day Tests.

DR. ADAM STATEN - GP VIEW AND RED FLAG SYMPTOMS

The ALEX® Allergy Explorer employs a quantitative solid-phase immunoassay methodology. In this process, specific IgE antibodies present in the patient's serum attach to the allergens (either extracts or components) situated on a microarray.

The introduction of a CCD-inhibitor serves to minimize non-specific reactions, thereby enhancing the test's specificity. To detect the presence of bound IgE antibodies, a colorimetric analysis is used, and hence the results of the test indicate the quantity of allergen-specific IgE, are reported quantitatively in units of kUA/l.

The higher the number - the more likely it is that an allergy is present to that product.

Red flag symptoms for the Ultimate Allergy Screening (ALEX 3.0) Blood Test

Even if your blood tests are normal, you should see a doctor if you have any of the symptoms below.

  • Unexplained weight loss
  • Persistent fevers
  • Night sweats
  • Unexplained bone pain

Your Results and Health Dashboard

The results of your Ultimate Allergy Screening (ALEX 3.0) Blood Test will be emailed to you as a secured PDF file, ready for your GP. Please note the Alex Allergy Screen is a separate large investigation and comes with it's own PDF and will not be available on the dashboard. It will be emailed to you separately.

SPECIAL INSTRUCTIONS

Hi, I am Stefania Brown, I am the Laboratory Manager at One Day Tests and here are the lab's special requests for the Ultimate Allergy Screening (ALEX 3.0) Blood Test.

SPECIAL INSTRUCTIONS

There are no special instructions for this test. You don't have to stop taking antihistamines, as antihistamines shouldn't affect the results of this blood test, unlike skin prick tests.

Clinic appointment - how to prepare for the Ultimate Allergy Screening (ALEX 3.0) Blood Test

If you are coming into one of our clinics for the test, this is what you need to do before you arrive:

  • Read the instructions in the SPECIAL INSTRUCTIONS section
  • Drink plenty of water about an hour before the appointment.
  • Avoid coffee/tea/energy drinks. Water is good!
  • That’s it! We’ll do the rest.

Home test kit - how it works with the Ultimate Allergy Screening (ALEX 3.0) Blood Test

Our blood test kits are simple and convenient.

The most important step in doing a blood test at home is to read the instructions very carefully. The process is very simple, but there are a few pitfalls you need to be aware of - you will save yourself a lot of time if you do it right the first time around!

  • Full printed instructions will arrive with your kit - please read them carefully.
  • Drink plenty before taking the sample and warm your hands up in the sink with warm water for a few minutes. This will make your blood flow much better.
  • Fill the tubes to the top line. We don’t need much blood; filling tubes to the top line is about 15 drops of blood.
  • Post the samples on the same day you take them, before midday, Monday to Thursday. If you post it any other time it might get to us late or be stuck at a sorting office over the weekend. You will then have to do it again.
  • Package the sample in the same box the kit came in. Otherwise, Royal Mail or DPD will reject it. The sample tubes go into a pouch, then into a cardboard box, and then into a return envelope. All of this is provided in the kit: please use it.

We look forward to receiving your sample in our lab!

FREQUENTLY ASKED QUESTIONS

Hi, I am Lana Nela, Lead Nurse, and here is what we are frequently asked about this test.

FREQUENTLY ASKED QUESTIONS

Here are some of the most frequently asked questions about the Ultimate Allergy Screening (ALEX 3.0) Blood Test.

What is IgE allergy testing?

IgE allergy testing is a diagnostic method used to identify specific allergens that trigger allergic reactions in an individual. IgE (Immunoglobulin E) is an antibody produced by the immune system in response to allergens, such as pollen, dust mites, pet dander, or certain foods. IgE antibodies play a central role in allergic responses. 

Why is IgE allergy testing better than IgG

IgE allergy testing is often considered better than IgG testing for allergies in specific scenarios because it is better suited for diagnosing immediate-type or Type I hypersensitivity reactions, which are more common and can lead to severe, potentially life-threatening allergic reactions.  

WHY HAVE THE TEST?
