Nephrology medical calculators

Kidney function, electrolytes, and renal dosing helpers.

Renal calculators estimate glomerular filtration rate, fractional excretion of sodium, free water deficit, and sodium correction needs. CKD-EPI 2021, Cockcroft–Gault, Schwartz pediatric eGFR, and electrolyte helpers appear frequently on medicine and ICU rounds. Results must be interpreted with muscle mass, diuretic use, and acute versus chronic kidney injury context.
