Input interpretation
transtubular potassium gradient
Equation
TTKG = (U_K S_osm)/(S_K U_osm) | | TTKG | transtubular potassium gradient S_osm | serum osmolality S_K | serum potassium U_osm | urine osmolality U_K | urine potassium
Input values
serum osmolality | 278 mOsm/kg (milliosmoles per kilogram) serum potassium | 4 mmol/L (millimoles per liter) urine osmolality | 500 mOsm/kg (milliosmoles per kilogram) urine potassium | 75 mmol/L (millimoles per liter)
Result
transtubular potassium gradient | 10.4%
