Renin and Aldosterone

DiaSorin offers the Hypertension line, in RIA format and on LIAISON® systems.

LIAISON® Direct Renin

The LIAISON® Direct Renin assay uses chemiluminescent immunoassay (CLIA) technology for the in vitro quantitative determination of renin in human EDTA-plasma specimens. Renin measurement is of help in the diagnosis and treatment of a number of hypertension types in humans. The test has to be performed on the LIAISON® Analyzer.

LIAISON® Aldosterone

The LIAISON® Aldosterone assay uses chemiluminescent immunoassay (CLIA) technology and is intended for the quantitative determination of Aldosterone in human serum, EDTA plasma and treated urine samples. Aldosterone measurements are intended for use in the diagnosis and treatment of primary aldosteronism (a disorder caused by excessive secretion of aldosterone by the adrenal gland), hypertension caused by primary aldosteronism, selective hypoaldosteronism, edematous states and other conditions of electrolyte imbalance. The test has to be performed on the LIAISON® Analyzer Family.


The DiaSorin Solution


Hypertension is classified as either primary (essential) hyperthension or secondary hyperthension; around 85-90% of cases are categorized as "primary hypertension" which means high blood pressure with no obvious underlying medical cause. The remaining 10-15% of cases (secondary hypertension) are caused by other conditions that affect the kidneys, arteries, heart or endocrine system. The hypertension caused by a treatable condition is mainly due to the so called Primary Aldosteronism and its early detection has the potential to prevent cardiovascular complications if treated appropriately.
Endocrine Society practice guidelines for the diagnosis and treatment of Primary Aldosteronism have highlighted the importance of ALDOSTERONE and RENIN testing. Aldosterone and Renin tests are usually requested by clinicians together when a patient shows high blood pressure and low potassium. Even if potassium is normal, testing may be done if typical medications do not control the high blood pressure or if hypertension develops at an early age.
