Laboratory inspection:

Serum sodium level <135mmol/L, extracellular fluid can be normal, increase or decrease. The plasma osmolality is <275mmol/L. Urine sodium determination helps to distinguish between renal and extrarenal sodium loss. The former is usually> 20 mmol/L, and the latter is usually less than 20 mmol/L.

Other auxiliary examinations:

1. The ammonium chloride stress test is helpful for the diagnosis of renal tubular acidosis.

2. Oral water load test patients take 20ml/kg of oral water load within 15-30min. They need to lie supine for 5h except for urination. Collect urine samples every hour to determine urine output and osmotic pressure. If 80% of the load water is excreted in the urine within 5 hours, it is normal that the osmotic pressure of the urine specimen is less than 100mOsm/kg at least once. If the drainage volume is less than 40% of the drinking water volume, and the urine osmotic pressure is greater than the plasma osmotic pressure, SIADH is indicated. This test is dangerous. It is forbidden for symptomatic hyponatremia or those whose blood sodium level is less than 125mmol/L.
