More information on the FirstStep Test

The FirstStep test is a cost-effective option to check for the presence of food intolerance through IgG testing. The analysis of IgG antibody levels in your blood will allow us to provide you with an easy to understand positive/negative result.

The FirstStep test is the indicator test; it will simply give a positive or negative result to ascertain whether or not you have a food intolerance. It will not mention any specific foods or food groups. 

We’re proud to say that we have a >98% reproducibility rate. This means that two separate tests carried out at the same time with the same person’s sample will correlate with each other >98% of the time.

Our laboratory and science are overseen by expert Biochemist, Dr Gill Hart who joined us in 2005 and has over 30 years’ experience in the development and validation of diagnostic tests and services. She steers the company’s research opportunities and product development, too! We understand putting your health into other people’s hands is a big deal, so you can find more on why you should trust and choose YorkTest here.

Our FirstStep test and full programmes work together hand-in-hand to help you discover your food intolerance but they both serve a different purpose.

Taking a FirstStep test with us is an exciting first step towards optimal help by providing you with a yes or no indicator for food intolerance. This testing option is ideal for those looking to see if there are raised food-specific IgG antibodies to foods in general in their blood.

If you were to test positive, you have the option to advance onto one of our full programmes to discover your individual food triggers. These full programmes indicate exactly what ingredients are causing a reaction, giving a thorough and detailed breakdown. We’ll also deduct the cost of the FirstStep test if you choose to upgrade. Plus there’s no need for an additional blood sample.

If you were to test negative, this means that the food-specific IgG antibodies to the foods that we measure are not raised. Therefore, you do not have a food intolerance.

Don’t worry, you don’t have to travel all the way to our laboratory in York to take the FirstStep test. We’ll send you a kit box with everything you need so you can take the finger-prick test in the comfort of your own home. All you need to do is follow the step-by-step instructions in the enclosed leaflet and send it back to us. You can also watch our video tutorial on how to collect your sample, fuss-free.

After you’ve sent back your blood sample for the FirstStep test, we promise not to leave you in suspense for long.

We have a quick turnaround, aiming to expertly test your sample and send your results back to you within 10 days. Everything happens in-house at YorkTest – from the expert analysis of your blood through to our friendly Customer Care team who will call you to discuss your result with you. Our expert team will be able to recommend a full programme for you based on your current symptoms and diet should you test positive at the FirstStep stage. Your original blood sample can be used if you choose to take one of our full test programmes.

Our full programmes include a thorough analysis of up to 208 food and drink ingredients, up to two 30-minute consultations with a nutritional therapist and extra content, such as guidebooks and a food and drink diary to help you along the way. Our Customer Care team are there to support you every step of the way, too.
