SCiO is NOT a medical device and should NOT be relied on to protect you from allergens under any circumstances.
SCiO works by measuring a small illuminated area of each material/object or food at a time, and therefore it cannot guarantee the absence of specific molecules on your plate, or within a serving. SCiO can analyze and tell you the major components of foods (i.e. typically those with concentrations of 1% or more), however, some allergens can be hazardous even in much lower concentrations and SCiO should never be used for this purpose.
