Understanding Your Results

Results should be interpreted by a qualified endocrinologist based on clinical context. Abnormal ratios may indicate adrenal disorders.
Elevated aldosterone with suppressed renin suggests primary hyperaldosteronism.
Low aldosterone with high renin may indicate secondary hyperaldosteronism or adrenal insufficiency.
Ratio values vary; refer to laboratory-specific ranges and physician guidance.
⚠️ When to Consult a Doctor:

Consult an endocrinologist if you experience symptoms like persistent high blood pressure, unexplained low potassium, muscle weakness, or fatigue, especially if you have a family history of adrenal disorders.
