Highlights

Slight variations in weight and volume of test materials can result in false positive results when testing dairy matrixes (such as cream cheese) for gluten using the Nima sensor, a personal, point-of-use gluten detection device.

Bottom Line

The gluten found results when testing certain dairy foods, such as cream cheese using the Nima sensor are likely false positives that appear to correspond with the weight and volume of the material tested, as well as the viscosity. There is also an apparent disconnect between the gluten found result reported by the sensor and an interpretation of the lateral flow device (LFD) strip result when assessed by eye which should also be taken into account (see photo)
