Hypophosphatemia
Diagnosis of Hypophosphatemia
Serum phosphate levels Hypophosphatemia is diagnosed by a serum phosphate concentration<2.5 mg/dL (<0.81 mmol/L). Most causes of hypophosphatemia (eg, diabetic ketoacidosis, burns, refeeding) are readily apparent. Testing to diagnose the cause is done when clinically indicated (eg, suggestive liver test results or signs of cirrhosis in patients with suspected alcohol use disorder).
