Aldosterone in Blood
An aldosterone test measures the level of
hormone made by the
adrenal glands) in the blood.
levels in a blood sample also change depending on whether you are standing up
or lying down at the time the blood is taken. Blood aldosterone levels will be
higher if you are standing or sitting up for 2 hours before the test.
The normal values listed here—called a reference range—are just a guide. These ranges vary from lab to lab, and your lab may have a different range for what's normal. Your lab report should contain the range your lab uses. Also, your doctor will evaluate your results based on your health and other factors. This means that a value that falls outside the normal values listed here may still be normal for you or your lab.
Results are usually available in 2 to 5 days.

An overgrowth of normal cells in the adrenal glands
(called adrenal hyperplasia) or a tumor of the adrenal glands affects the
adrenal glands directly and causes a condition called primary aldosteronism.
Certain diseases such as
cirrhosis, or kidney disease can also cause high
aldosterone levels, but this is a normal response by the adrenal glands. These diseases cause
Aldosterone and renin levels

| Secondary hyperaldosteronism
High aldosterone levels can be caused
- A tumor in the adrenal glands (Conn's syndrome).
- Liver disease.
- Heart failure.
condition during pregnancy that causes high blood pressure (preeclampsia).
Symptoms of a high aldosterone level include
high blood pressure, muscle cramps and weakness,
numbness or tingling in the hands, and low levels of potassium in the
Addison's disease and some types of kidney disease may cause low aldosterone levels.
