Calculated and context-dependent. Not a stand-alone diagnostic marker.
Calculated; interpret component values.
Muscle mass, age, diet, medications, and assay matter. Review with eGFR, not alone.
Inflammation, hydration, liver synthesis, renal loss, and nutrition affect result.
Approximate risk strata are sex-specific and assay-dependent.
Spot urine is useful mainly for populations; individual status requires careful collection and interpretation.
Color and clarity are nonspecific; review medications, hydration, and sediment.
Diet, infection, medications, and specimen age affect result.
Dipstick is albumin-biased. Confirm persistent findings with quantitative ratio.
Renal threshold, SGLT2 inhibitors, pregnancy, and hyperglycemia matter.
