Restaurant: Burger King, 4424 Broadway, Oakland CA
Food: french fries
Results: negative for gluten to 5 PPM
Date: 2015 August 9
Notes: The negative result is based on the test kit's instructions to wait no more than 10 minutes for the result. However, about 10 minutes later, the result showed indications of a positive test (a faint red line) - as shown in the second photo below. Per the email appended below, the test kit company's representative states that this late result indicates that there is some gluten, but below the 5 PPM threshold.
