Aldosterone Inferior Vena Cava

Also known as: ALDO IVC

Clinical Use

Use

This test is used to investigate primary and secondary aldosteronism through measurement of aldosterone levels in the inferior vena cava. It assists in diagnosing conditions related to aldosterone imbalance, such as primary aldosteronism, which can cause hypertension and other cardiovascular issues. Adrenal venous sampling is required to collect the specimen, making the test highly specific to assess aldosterone levels from the adrenal glands directly.

Special Instructions

Not provided.

Limitations

False-positive or false-negative results may occur due to various factors, including patient preparation and improper specimen collection. Medications used for hypertension control can influence aldosterone levels, affecting the aldosterone-renin ratio (ARR), potentially leading to misinterpretation of results. It is crucial to ensure patient adherence to pre-test instructions and consult comprehensive guidelines to minimize risks of inaccurate outcomes.
