Important Updates to NutrEval®
We've Updated and Simplified the Collection Process for the NutrEval®
Updated blood collection and processing steps will be implemented for our NutrEval. To facilitate this update, we have designed a new NutrEval kit. The label shown here will notify the phlebotomist of the revised test components and instructions. The link below provides further details of the specimen matrix updates.
When you see the reminder label, simply follow the collection process instructions included within the labeled kit.
If you DO NOT see the update reminder label on your Elemental Analysis kit, follow the collection process included within that test kit.
Specimen-Matrix Updates
Elemental Markers are currently measured in red blood cells (RBCs) specimen matrix. The updated collection process is part of a change to this specimen matrix. Additionally CoQ10 will be measured in serum.
