Name the elements
Sodium, calcium, potassium, iron and other elements should be requested by name. A generic minerals request can leave uncertainty about which elements are included.
Describe the product and purpose
Tell us whether the sample is a finished food, an ingredient or a development version. Include whether the result supports a nutrition value, a specification or a comparison.
Use consistent units
Concentration, serving size and product preparation affect how a result is expressed. Keep the sample basis and any dilution or reconstitution instructions with the request.
Separate nutrition from contaminants
A nutrition-mineral panel and a toxic-element investigation are different scopes. Name any contaminant targets separately and establish reporting requirements that fit the decision.
