eGFR CKD-EPI 2021
Estimates glomerular filtration rate from serum creatinine, age, and sex.Cockcroft-Gault Creatinine Clearance
Estimates creatinine clearance for medication dose adjustment.Urine Albumin-Creatinine Ratio (uACR)
Albumin-to-creatinine ratio (ACR) is the first method of preference to detect elevated protein.Calculated Serum Osmolality
Estimates serum osmolality from sodium, glucose, and BUN.Serum Anion Gap
Evaluates states of metabolic acidosis.Corrected Sodium in Hyperglycemia
Corrects serum sodium when glucose is elevated.Albumin-Corrected Calcium
Approximate total calcium correction when albumin is abnormal.Free Water Deficit
Estimates water deficit in hypernatremia.FENa - Fractional Excretion of Sodium
Determines if renal failure is due to prerenal or intrinsic pathology.FEUrea - Fractional Excretion of Urea
Determines the cause of renal failure. Similar to the FENa, but can be used on patients on diuretics.RIFLE Criteria for Acute Kidney Injury (AKI)
Classifies AKI severity using creatinine or GFR change and urine output criteria.Kidney Failure Risk Equation (4-variable)
Estimates 2-year and 5-year kidney failure risk.Transtubular Potassium Gradient (TTKG)
May help in patients with hyper- or hypokalemia (defined as K+ <3.5 or >5.0 mEq/L in this calculator).No calculators found.
