Metabolic, Kidney & Electrolytes — Reference Ranges
This group covers the blood chemistry panels — electrolytes, kidney function, blood sugar, and the minerals and proteins that travel with them. The basic and comprehensive metabolic panels are drawn from this group, and because a kidney specialist reads these numbers every day, this is a special focus of this site.
This page lists all 23 tests in this group with their typical adult ranges in both unit systems. Open any test for plain-language notes on high and low results and how to prepare.

Please note: Reference ranges vary between laboratories, and between the methods and instruments they use — the range printed on your own report is the one your result should be compared with. A result outside the range is not by itself a diagnosis, and a result inside it does not rule out illness. These pages are an educational summary, not medical advice: always discuss your results with the clinician who ordered them, who can interpret them in the context of your health and history.
