Liquid IV: Statement from Gluten Free Watchdog
Gluten Free Watchdog received several complaints about this product from consumers after they tested Liquid IV using lateral flow devices, including EZ Gluten and Nima Sensor and received positive results for gluten. A consumer’s retained sample and a new box of the same flavor of Liquid IV were tested at Bia Diagnostics, LLC (an accredited laboratory) using the fully validated sandwich R5 ELISA, the competitive R5 ELISA, and EZ Gluten test strips.
When the product was tested using the sandwich and competitive R5 ELISAs, no detectable gluten was found. Note: results are reported by the lab as < 5 ppm and < 10 ppm which is below the lower limit of quantification for gluten for the two assays used. However, the samples also tested below the lower limit of detection, testing at the zero standard.
When the recommended weight amount of sample was tested using EZ Gluten test strips, the result was negative for gluten.
False positive results were found when more than the recommended weight amount of product was tested using the EZ Gluten test strips.
Consumer testing of food with lateral flow devices may sometimes lead to false positive results. This is due to several factors, including the ingredients present and how the food is sampled for testing.
