Bands are given in the marker's canonical unit; values in other units are converted automatically.

Why it matters on a plant-based diet

Vegans get provitamin beta-carotene, which must be converted to retinol. Conversion is limited and depends on zinc (needed for retinol-binding protein) and thyroid status.

A single marker decides nothing

Deficiencies mask one another: high folate hides low B12, inflammation inflates ferritin, low zinc mimics iron deficiency. VEGALYSIS reads the whole picture and explains the links.
