Aldosterone-renin ratio (AR)
1,500 UAH
Aldosterone-renin ratio (AR) — a calculated diagnostic indicator that assesses the balance between the hormones aldosterone and renin for primary screening of hyperaldosteronism.
Why is it prescribed: for detecting primary hyperaldosteronism in patients with arterial hypertension (especially resistant to drug treatment), clarifying the causes of hypokalemia, as well as for differential diagnosis of forms of endocrine hypertension.
Material for research: venous blood (venous plasma/serum).
Method: calculation method based on laboratory measurement of aldosterone concentrations and renin activity/concentration (ELISA/CLIA).
Interpretation of results and correction of therapy are carried out exclusively by the attending physician.
Aldosterone and renin in the body interact in a complex system, known as the aldosterone-renin ratio (ARS). This system regulates blood pressure and blood volume by controlling the body's water and electrolyte balance.
Analyses
Various tests are performed to assess the function of the ARS and diagnose disorders related to this system. Among them, an important place is taken by measuring the levels of aldosterone and renin in the blood. High levels of aldosterone may indicate hyperaldosteronism, while low levels may be associated with hypoaldosteronism.
Additional tests that may be performed include measuring the concentration of electrolytes in the blood, such as sodium, potassium, and chloride, as aldosterone affects their levels.
Hormonal panel/Hypothalamic-pituitary-adrenal system
The hypothalamic-pituitary-adrenal (HPA) axis also needs to be considered when analyzing ARF function. This axis controls the production and release of renin and other hormones that affect adrenal function and aldosterone.
In case of disturbances in the functioning of the GNH system, a number of pathological conditions may arise, such as primary and secondary hypo- and hyperaldosteronism. Therefore, it is important to conduct a comprehensive analysis to understand the state and functioning of both systems and their interrelationship.
