Why Is This Test Done?
Your doctor may order this test to check for conditions like primary aldosteroneism (also called Conn’s syndrome), adrenal gland issues, or to monitor treatment for high blood pressure or other hormonal imbalances. It can also help diagnose conditions affecting your kidneys or adrenal glands.
What Does a High or Low Level Mean?
High aldosterone levels may suggest overactivity of your adrenal glands or certain kidney problems. Low levels could indicate adrenal insufficiency or other hormonal disorders. Your results will be compared to standard reference ranges provided by your lab.
How Is This Test Performed?
A blood sample is taken from a vein in your arm. The sample is sent to a lab where it is processed to measure aldosterone concentration using a specialized analytical method.
What Should You Expect Before the Test?
No special preparation is usually needed, but your doctor may advise avoiding certain medications or dietary restrictions depending on your specific situation.
