“…Hypokalemia was evaluated by further spot urine potassium and spot urine creatinine. The results were as follows: urine creatinine 2551 umol/L, urine potassium 11 mmol/L, and urine potassium creatinine ratio 4.31 mmol/L which indicated that hypokalemia was due to increased renal loss of potassium [ 1 ]. Urine potassium value may depend on the amount of potassium in diet and the amount of potassium in the body.…”

Primary aldosteronism is one of the causes of secondary hypertension. The most sensitive screening test for primary aldosteronism is the measurement of the plasma aldosterone concentration and plasma renin activity to calculate the aldosterone/renin ratio. We report a case of hypertension and hypokalemia with a negative plasma aldosterone/renin ratio, inconclusive confirmatory saline infusion test. Subsequently, the patient was diagnosed with primary aldosteronism secondary to adrenal adenoma. If there is a high index of clinical suspicion of primary aldosteronism, it is important to evaluate further to establish the diagnosis for initiation of specific treatment because failure to identify primary aldosteronism can lead to aldosterone-specific adverse cardiovascular diseases and events.
