LIAISON® Hypertension Diagnostic Solution

A comprehensive solution for primary hyperaldosteronism screening.

The hypertension panel is the first automated solution for accurate diagnosis of primary hyperaldosteronism, a secondary form of hypertension. The solution includes additional endocrine markers related to the adrenal function.


LIAISON® Aldosterone

Automated CLIA assay for the quantitative determination of aldosterone, whose measurements are used as an aid in the diagnosis of hypertension due to primary and secondary hyperaldosteronism. 


LIAISON® Direct Renin

Automated CLIA assay for the quantitative determination of direct renin, whose measurements are used as an aid in the diagnosis of hypertension as due to primary and secondary hyperaldosteronism.

Indications for use


Quantitative assays for the screening of primary aldosteronism and diagnosis of other adrenal functions

Target patient

Adults hypertensive patients, patients with endocrine disorders

Use area

Hypertensive centers, cardiology, endocrinology and nephrology centers

Solution for the diagnosis of Hypertension and Hyperaldosteronism - Diasorin


A major cause of premature death worldwide,
over 1.3 billion people suffer from hypertension.

Primary hyperaldosteronism prevalence is seen in at least 10% of hypertensive patient and up to 25% in patient with resistant hypertension. Despite the Endocrine Society guidelines and recommendations, it is often underdiagnosed. 
Reliable and easy to use, LIAISON® Aldosterone and LIAISON® Direct Renin tests help determine the Aldosterone to Renin Ratio calculation, supporting physicians by providing a fundamental step in the assessment of hypertensive patient and guiding clinicians in the management of such patient.
The fully automated and guidelines-approved approach also ensures better laboratory operational efficiency.

How it works

The LIAISON® Aldosterone assay demonstrates 100% specificity for aldosterone with no cross-reactivity with other major steroid hormones.

A quantitative assay for the determination of aldosterone 


Automated aldosterone measurement

Ideal solution for automated aldosterone measurement in plasma, serum and urine samples.


Complete clinical picture of the hypertensive patient

It can be consolidated with automated LIAISON® Direct Renin to gain a complete clinical picture of the hypertensive patient in a single EDTA plasma sample tube.



Flexibility, consolidation and automation.

A quantitative assay for the determination of direct renin



Use of monoclonal antibodies to measure renin concentration independent of substrates, and long temperature/pH dependent incubation periods.


Automated Direct Renin measurement

The fully automated LIAISON® Direct Renin assay is a faster, simpler, more reproducible alternative to Plasma Renin Activity (PRA) assays.

Why use it

Why use Diasorin Aldosterone and Direct Renin tests

Diasorin makes screening for primary aldosteronism simple and fast by consolidating aldosterone and direct renin measurements into a single EDTA plasma sample tube.

ARR determination

The LIAISON® Aldosterone and LIAISON® Direct Renin tests are a reliable, accurate and simple to use method for determining Aldosterone- to- Renin Ratio (ARR), which is considered as the screening tool for PA diagnosis in patient with hypertension.

Adrenal function

ACTH and cortisol are two important markers related to adrenal function. ACTH and cortisol levels in the blood are tested to help diagnose Cushing's syndrome, Addison's disease, and tumors of the pituitary and adrenal glands.

With high disease prevalence, reliable and convenient diagnostic tools are imperative

Our solution includes the right tools to help labs convert from PRA to DRC for improved workflow, accurate diagnosis and better patient care.

Simplify hypertension testing

LIAISON® Aldosterone and LIAISON® Direct Renin are specialty tests making our solution an ideal fit for laboratories looking to automate hypertension testing.
