When reading the tray, the positive control should be read as 5, and the negative as 0. Rate other reactive foods in comparison to these and move the cursor to the appropriate spot on the table (left) to generate a report.

Identify the Reactive Foods

Foods are located in positions 1 – 46 of the reaction tray.

Deep blue spots denote a strong reaction, and paler spots represent mild reactions. If foods remain white, this denotes a negative result. If a food item shows a thin ring around the food item, but not in the centre, this is also a negative result.

Good luck with the test!
