Your Lab Values Are Normal
Your serum sodium of 141 mmol/L and ADH of 0.8 pg/mL are both within normal ranges and require no intervention. 1
Understanding Your Results
Serum Sodium Level
- Normal range: 135-145 mmol/L 1
- Your value of 141 mmol/L falls comfortably in the middle of this range
- This indicates proper water balance and normal kidney function 2
ADH (Antidiuretic Hormone) Level
- Normal range: 0.0-4.7 pg/mL 1
- Your value of 0.8 pg/mL is appropriately low-normal
- This level is consistent with your normal sodium concentration 3
What This Means Physiologically
Your body's water regulation system is functioning properly. 4
- With normal serum sodium, your osmoreceptors are not triggering excessive ADH release 3
- The low-normal ADH level (0.8) indicates your kidneys are appropriately excreting free water without excessive retention 5
- This represents normal osmoregulation—your thirst mechanism and ADH secretion are working in harmony 4, 3
No Action Required
You do not need:
- Fluid restriction 1
- Sodium supplementation 1
- Any medication adjustments 1
- Further workup for sodium disorders 2
When to Seek Medical Attention
Contact your physician if you develop:
- Symptoms of hyponatremia: nausea, headache, confusion, weakness, or seizures (sodium <135 mmol/L) 2
- Symptoms of hypernatremia: excessive thirst, confusion, or altered mental status (sodium >145 mmol/L) 2, 6
- Significant changes in urination patterns 3
Your results indicate normal water and electrolyte homeostasis with no evidence of SIADH, diabetes insipidus, or any other disorder of water metabolism. 5, 3
