Diagnosis of Liddle Syndrome
Urine sodium level Plasma renin andaldosteronelevels Diagnosis is suggested by the presence of hypertension in a young patient, particularly one with a positive family history. Low urine sodium (<20 mEq, or 20 mmol/L), low plasma renin andaldosteronelevels, and response to empiric treatment usually are considered sufficient to confirm the diagnosis. Definitive diagnosis can be achieved through genetic testing (seeGeneTestsfor more information) .
