About the FirstStep Test

As individuals, our reactions to foods and drinks vary a great deal. An ingredient which may cause problems for one person could be completely acceptable for another. At YorkTest, we like to refer to this as our ‘food fingerprint’.

Understanding your own personal food and drink intolerances, and the effects they could have on your health and wellbeing, is important to ensuring you make the best possible choices for your diet.

The YorkTest FirstStep is ideal for discovering whether food-specific IgG antibody reactions are present in your blood before progressing to one of our complete YorkTest programmes. Learn more

Why Choose the FirstStep Test?

  • The test is a pre-screen for IgG antibody reactions to foods
  • If positive, progress to either the comprehensive FoodScan, Food&DrinkScan, Ideal Weight Programme or IBS Diet Programme
  • Easy to use, finger prick blood test which can be taken in the comfort of your home
  • Laboratory analysed results
  • Customer care support and advice
  • Convenient mail order postal service; no need to visit our laboratory

What to Expect from the FirstStep Test

The YorkTest FirstStep kit contains all you need to take a small blood sample (2 – 3 drops) in the comfort of your own home. Simply return your sample in the pre-paid envelope provided (UK only) to our York laboratories for expert analysis. Your confidential results are then posted to you within ten days.

If you get a positive result* you will be able to progress on to one of our tailored complete programmes. Our complete programmes are supported by essential guidance and advice from our BANT** registered Nutritional Therapists to enable you to eliminate your trigger foods and optimise your diet.

If you get a negative result then you do not have food-specific IgG reactions present. Our Customer Care Team will talk you through other testing options available to you.

N.B. Raised levels of food-specific IgG antibodies within your blood indicate that an IgG antibody reaction to a particular food or foods has occurred. If you have already taken the decision to eliminate a particular food or foods from your diet they may not show up as a reaction on your results. If you know of foods that trigger your symptoms then do not start eating them; we do not encourage you to eat a food or foods which you already know are a problem to you.

After many years of IBS symptoms - bloating, constipation, etc - and not really getting anywhere with my GP, I decided to try the York Test. It was well worth it - my profile came back with several intolerances of pretty major food groups and I was at first worried about how I'd cope. The nutritionists were very helpful and gave sound advice on the way to approach dealing with my particular intolerances. Since cutting out these foods I have been much better - no bloating or cramps (other than when I ordered an old/me meal one day and paid for it with severe cramps within 40-50 minutes!) Well worth the money for establishing potential problem foods and I was very glad I took the plunge.
