Overview
The lab findings which help in diagnosis of SIADH are serum electrolytes (especially sodium), creatinine, BUN, serumuric acid, serum cortisol, and plasma ADH level. Urine osmolality, urinesodium level andGFR are also of diagnostic significance.
Laboratory Findings
Lab findings consistent with the diagnosis of SIADH are;
- Decreased serum sodium (<135 meq/l)
- Decreased serumosmolality(<280mosm/kg)
- Low BUN levels
- Low albumin levels
- Low uric acid
- NormalCreatinine
- Normal thyroid hormones
- Normalcortisol
- Increased GFR
- Increased plasma ADH levels[1]
