Description
Transtubular potassium gradient (TTKG) is an index reflecting the conservation of potassium in the cortical collecting ducts of the kidneys. It is useful in diagnosing the cause of hyperkalemia.

Formulas Used:
TTKG = (Urine K * Plasmaosm) / (Plasma K *Urineosm)

Where,
TTKG = Transtubular Potassium Gradient
Urine K = Urine potassium (in mEq/L or mmol/L)
Plasma K = Plasma potassium (in mEq/L or mmol/L)
Plasmaosm = Plasma osmolality (in mOsm/kg or mmol/kg)
Urineosm = Urine osmolality (in mOsm/kg or mmol/kg)
