Aldosteronism (Conn’s Syndrome) Blood Panel (Labcorp)
This panel includes several tests which can aid in diagnosing Primary Aldosteronism. Aldosteronism, also known as Conn's Syndrome, is a condition in which the adrenal glands produce an excess of the hormone aldosterone. This causes the body to retain sodium which leads to high blood pressure. The causes of Aldosteronism vary but it is most often the results of benign tumors on the adrenal glands. High blood pressure caused by aldosteronism is associated with an increased risk of heart attack or stroke. Identifying and treating this condition early is important to help avoid serious health complications.
This package includes:
- Renin Activity, Plasma
- Aldosterone:Renin Ratio
- Cortisol, Blood
These blood tests are often ordered when a person has unexplained high blood pressure, especially if they are not responding to blood pressure medication. People with Aldosteronism/Conn's Syndrom will often show higher than normal levels of aldosterone along with low levels on Renin. Renin is an enzyme which plays an important role in the body's process of controlling blood pressure. Measuring Cortisol levels can also help determine the cause of abnormal aldosterone levels since Cortisol is also produced by the adrenal glands.
Turnaround for these tests is typically 3-7 business days.

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
Maintain an unrestricted dietary salt intake prior to testing. Washout of all interfering antihypertensive medications may be considered in people with mild hypertension, but is potentially problematic in others and perhaps unnecessary in that medications with minimal effect on the ARR can be used in their place. Do not take drugs that markedly affect the ARR for at least four weeks prior to blood collection. These drugs include Spironolactone, eplerenone, amiloride, and triamterene Potassium-wasting diuretics, and Products derived from liquorice root (eg, confectionary licorice, chewing tobacco).
Collect blood mid-morning, after being up (sitting, standing, or walking) for at least two hours and seated for 5 to 15 minutes.
It is recommended that someone taking Biotin (also known as vitamin B7 or B8, vitamin H, or coenzyme R) stop consumption at least 72 hours prior to the collection of a sample.
