The ratio between serum sodium and serum osmolality is helpful in predicting prognosis in many conditions. The low ratio in conditions like Lymphoma, Cancer, Liver failure, Acute Infections, and Myocardial infarction is predictive of an unfavorable prognosis. In cases of Acute toxicity due to drug overdose like salicylate poisoning, findings of normal ratio are often considered as an indication of dialysis. In dehydration, when water loss exceeds salt loss both serum osmolality and sodium levels increase, but the ratio remains normal. |
