Understanding Ranges

Reference range — the clinical "normal" range used by labs. Values outside this range are flagged as low or high.

Optimal range — a narrower band associated with better health outcomes in research. Values within reference but outside optimal are marked "suboptimal".

Always consult a healthcare provider for interpretation of your specific results.
