How our test process works!
aldosterone is called hyperaldosteronism. This extra aldosterone causes high blood pressure and low potassium levels. Sometimes it can look like moderate to severe high blood pressure and go undiagnosed for a long time.
An aldosterone (ALD) test is mainly used with a renin test to find out whether too much ALD is the cause of high blood pressure that: Happens with low potassium levels. Doesn't improve with usual blood pressure medicines.
0 - 30 ng/dL, or 0.00 - 1081.35 pmol/L
A higher than normal level of aldosterone may be due to:
* Bartter syndrome (group of rare conditions that affect the kidneys)
* Adrenal glands release too much aldosterone hormone (primary hyperaldosteronism - usually due to a benign nodule in the adrenal gland)
* Very low-sodium diet
* Taking blood pressure medicines called mineralocorticoid antagonists
* Abuse of diuretics
* Liver cirrhosis
* Heart failure
* Laxative abuse
Adrenal adenomas (noncancerous tumors) are the most common cause of primary hyperaldosteronism. Rarer causes of primary hyperaldosteronism include: Unilateral adrenal hyperplasia (one enlarged adrenal gland). Aldosterone-producing adrenocortical carcinomas (cancerous tumors).
Lower than normal level of aldosterone may be due to:
A lower than normal level of aldosterone may be due to:
* Adrenal gland disorders, including not releasing enough aldosterone, and a condition called primary adrenal insufficiency (Addison disease)
* Very high-sodium diet

Frequently Asked Question
Aldosterone Serum testing may be ordered when a patient presents with symptoms suggestive of conditions affecting the RAAS, such as hypertension, hypokalemia (low potassium levels), alkalosis, or symptoms of aldosterone excess (e.g., muscle weakness, fatigue, headaches).
Patients may be instructed to fast overnight before the blood test, and certain medications that can interfere with aldosterone levels may need to be temporarily discontinued before testing. It is essential to follow any instructions provided by the healthcare provider.
Aldosterone Serum testing is performed to diagnose and monitor conditions related to abnormal RAAS activity, such as primary aldosteronism (Conn's syndrome), secondary aldosteronism, hypertension (high blood pressure), and electrolyte imbalances.
Aldosterone Serum testing can be performed in medical laboratories or healthcare facilities equipped with the necessary equipment and expertise. It is typically ordered by healthcare providers, such as endocrinologists, nephrologists, or primary care physicians, based on clinical indications.
Coverage for Aldosterone Serum testing may vary depending on the healthcare provider, insurance plan, and reason for testing. It is essential to check with the insurance provider regarding coverage and any associated costs before undergoing testing. In some cases, Aldosterone Serum testing may be covered as part of routine diagnostic evaluation for hypertension or other related conditions.
Aldosterone Serum testing involves collecting a blood sample from the patient, typically in the morning after overnight fasting. The blood sample is then analyzed in a laboratory to measure the level of aldosterone hormone using immunoassay techniques.
Aldosterone Serum testing measures the level of aldosterone hormone in the blood. It helps evaluate the function of the renin-angiotensin-aldosterone system (RAAS), which regulates blood pressure and electrolyte balance.
The results of Aldosterone Serum testing help healthcare providers assess the activity of the RAAS and diagnose conditions such as primary aldosteronism (elevated aldosterone), secondary hyperaldosteronism (elevated aldosterone due to non-adrenal causes), or other adrenal gland disorders affecting aldosterone production.
