About this test

The Aldosterone Blood Test measures the level of aldosterone, a hormone produced by the adrenal glands that plays a key role in regulating blood pressure and fluid balance. Aldosterone helps control how much sodium and water the body retains and how much potassium is excreted through the kidneys.

When aldosterone levels are too high, a condition known as aldosteronism can develop. Excess aldosterone causes the body to retain sodium and water while losing potassium, which can lead to persistent high blood pressure that is difficult to control with standard treatment.

This test is especially useful for identifying hormonal causes of hypertension, particularly in individuals whose blood pressure remains elevated despite medication. Detecting abnormal aldosterone levels can help uncover an underlying endocrine condition that may otherwise go undiagnosed.

By identifying aldosterone imbalance early, this test supports targeted treatment decisions that can improve blood pressure control, reduce cardiovascular risk, and protect kidney health over time.


What Is Included In This Test?

This test measures the concentration of aldosterone in your blood.

Your results can help: Determine whether aldosterone levels are elevated

  • Identify hormone related causes of high blood pressure
  • Guide further adrenal or kidney evaluation
  • Support diagnosis of aldosteronism
  • Inform personalized treatment strategies

Results are typically interpreted alongside other clinical findings and hormone tests.


Why Does This Test matter?

High blood pressure is a major risk factor for heart disease, stroke, and kidney damage. When hypertension is caused by excess aldosterone, standard treatments may be less effective unless the hormonal imbalance is addressed.

Elevated aldosterone can silently strain the cardiovascular system by increasing fluid volume and narrowing blood vessels. Over time, this can lead to long term complications if not properly identified and managed.

This test helps distinguish primary aldosteronism from other causes of hypertension, allowing for more precise treatment such as targeted medications or further adrenal evaluation.

Early detection can significantly improve outcomes by reducing blood pressure related complications and improving overall cardiovascular health.


Who Should Consider This Test?

This test is ideal for individuals with risk factors or symptoms related to hormone driven hypertension.

You should consider this test if you:

  • Have high blood pressure that is difficult to control
  • Have low potassium levels
  • Were diagnosed with hypertension at a young age
  • Have a family history of endocrine or adrenal disorders
  • Have hypertension with no clear cause
  • Are being evaluated for secondary causes of high blood pressure

Identifying the root cause of hypertension allows for more effective and lasting treatment.
