TTKG Calculation
About TTKG
The transtubular potassium gradient (TTKG) assesses renal potassium handling and helps differentiate causes of hyperkalemia.
TTKG Formula:
TTKG = (Urine K / Serum K) × (Serum Osm / Urine Osm)
Interpretation:
- <3: Inadequate K+ secretion
- 3-7: Normal K+ handling
- >7: Excessive K+ secretion
Clinical Uses:
- • Hyperkalemia evaluation
- • Hypokalemia assessment
- • Renal function evaluation
- • Medication effects
Limitations:
- • Requires urine collection
- • Affected by hydration
- • Diurnal variation
- • Medication interference
Professional Resources:
- • Nephrologist
- • Endocrinologist
- • Primary care physician
