Overview

Lab findings helpful in diagnosing SIADH, include serum electrolytes,especially sodium,BUN,creatinine, glucose levels, and osmolality. Patients with syndrome of inappropriate antidiuretic hormone may be characterised with hyponatremia (sodium <135 mEq/L) and low serum osmolality (<280 mOsm/kg). Patients with syndrome of inappropriate antidiuretic hormone show elevated urinary sodium level (>20 mmol/L) and urine osmolality (generally >100 mOsm/L). They also have low BUN, normal creatinine,low uric acid and low albumin.
