ALDOSTERONE

The ALDOSTERONE test measures the concentration of aldosterone, a hormone produced by the adrenal glands that helps regulate sodium, potassium and blood pressure. A blood sample is analysed in an accredited laboratory to provide accurate quantitative results used in the assessment of adrenal function and disorders of mineralocorticoid balance.

This test is primarily used to screen for and diagnose conditions such as primary aldosteronism, to evaluate unexplained or resistant hypertension, and to investigate persistent hypokalaemia or adrenal incidentalomas. In Dubai, you can arrange convenient at‑home sample collection by a certified phlebotomist with fast reporting from UAE‑accredited labs; interpretation and any medication adjustments should be done under physician guidance.

• Plasma Aldosterone Concentration (PAC)

• Aldosterone‑to‑Renin Ratio (ARR)
• Serum Potassium

• Resistant or difficult‑to‑control hypertension
• Unexplained or recurrent low potassium (hypokalaemia)
• Suspected primary aldosteronism
• Evaluation of an adrenal incidentaloma
• Monitoring response to aldosterone‑blocking treatment

• Accurate detection of aldosterone excess and mineralocorticoid disorders
• Guides targeted treatment for hypertension (medication or referral for surgery)
• Helps identify and correct electrolyte imbalances (sodium/potassium)
• Convenient at‑home blood collection in Dubai with UAE‑accredited lab analysis
• Fast, reliable results to support timely clinical decisions

• Morning venous blood sample preferred; follow specific posture/timing instructions given by your clinician
• Inform your physician about all medications—some antihypertensives, diuretics and mineralocorticoid antagonists may need temporary adjustment under medical supervision
• Avoid potassium supplements or large changes to dietary potassium unless instructed
• At‑home collection performed by a certified phlebotomist; suitable for adults and reported by accredited UAE laboratories
