What this is, in plain language
A blood test that checks eight things at once: kidney function (creatinine, BUN), blood sugar, and electrolytes like sodium and potassium.
Why a clinician orders it
Routine checkups, monitoring kidney function, checking electrolytes before procedures, or evaluating dehydration and medication effects.
Medical necessity — what insurers usually look at
