DAldosterone levels can be influenced by body position and sodium intake. Remaining in a consistent position (supine or upright) for at least 2 hours prior to the test helps standardize the results, as aldosterone levels can vary with changes in posture. Restricting sodium in the diet for a week prior to the test can help in assessing the body's aldosterone response to sodium intake, as aldosterone plays a key role in sodium regulation in the body.
