Test Kit: Imutest Gluten-in-Food Kit
Preparation: For testing beer the gluten extraction process described in the instructions can be skipped as the gluten in beer is already solubilised. Find some more information here. Beside the test kit and beer sample have a stopwatch handy.

The pictures below describe the test process (from left to right).

Test result: There seems to be no gluten in Corona. According to the instructions there should appear a clearly visible pink test spot on the left of the test area ( T ) to indicate the presence of gluten. But there is absolutely nothing to see. The pink spot on the right test area ( C ) is a control spot and indicates that the extract/sample is suitable, the test has been performed correctly and all reagents are active. Even though the detection limit in this kit is very low (1-2 ppm) this test is not a medical advice – please see my facts page.
