The comparison bar shows each product's measured amount as a share of the highest result in this group — the fullest bar simply has the most of the selected analyte, not 100% of any health limit. When a regulatory limit sits close to the readings, the bars scale to that limit instead and it appears as a dotted marker.
Requested Test: Heavy Metals Panel
Tests for lead, arsenic, cadmium, and mercury — toxic metals that can accumulate in the body over time and cause neurological, kidney, and developmental harm, even at low levels.
How The Test Is Performed
The food sample is broken down with acid, then heated into a plasma (an extremely hot gas) that strips the metals into individual atoms. A detector (ICP-MS) then counts each type of metal atom, identifying exactly how much lead, arsenic, cadmium, or mercury is present — even at parts-per-billion levels.
