First Step - Indicator Test

FirstStep Test

The YorkTest FirstStep Test quickly determines whether IgG antibody reactions to foods and drinks are detected in your blood or not.

If you get a positive result then purchase the FoodScan Programme (£245†), Food&DrinkScan Programme (£289†) or IBS Diet Programme (£289†) or Ideal Weight Programme (£289†) to discover what foods you have reacted to.

If you get a negative result then you do not have food-specific IgG reactions present and therefore no further testing is required.
