Innovative RAAS Triple-A™ profiling to support clinical management and research in hypertension


A unique laboratory test to tackle uncontrolled hypertension

High blood pressure is the number one cardiovascular risk factor worldwide and contributes to more than 9 million deaths per year. 

We offer an innovative and unique lab test for patients with uncontrolled hypertension, supporting physicians to find the optimal therapy for their patients. With the innovative RAAS Triple-A™ LC-MS/MS Kit, we provide a diagnostic tool to simultaneously screen for secondary hypertension and monitor pharmacologic effects of antihypertensive drugs. 

We support researchers, doctors and laboratories by providing access to highly accurate and robust analytic methods for assessing the Renin-Angiotensin-Aldosterone-System (RAAS) in clinical samples.

Our vision is to improve hypertension control by simplifying the diagnostic workup. RAAS Triple-A analysis helps to identify the most common causes of uncontrolled hypertension, paving the way for a personalized and more effective treatment.

“After almost a decade of developing the RAAS Triple-A™ approach, we finally have a product in hands that already effectively helps patients. I couldn’t be more excited to see how the broad availability of robust angiotensin biomarkers in clinical routine will transform clinical management of uncontrolled hypertension. I think it could be a real gamechanger.”

Marko Poglitsch, PhD

CEO, Attoquant Diagnostics

“The RAAS Triple-A™ assay was a huge improvement for us. We were struggling with the robustness and the interpretation of classical RAAS markers like renin and aldosterone. By integrating RAAS dynamics and anti-hypertensive drug effects, the RAAS Triple-A™ test delivers much more information than classical assays, being beneficial for doctors and patients on our clinic.”

Univ. Prof. Dr. Marcus Säemann

President of the Austrian Society of Nephrology

“RAAS Triple-A™ profiling is a simple and robust serum test that was applied in more than 700 patients in specialized centers in Austria in the last two years. Over 150 patients were screened positive for primary aldosteronism. We received very encouraging feedback from endocrinologists, nephrologists, and cardiologists.”

Univ. Doz. Dr. Markus Exner


“I was desperate after having tried different anti-hypertensive therapies for years. RAAS Triple-A™ helped my doctor to identify a special form of hypertension that needs special treatment. My blood pressure is under control now and I even have less pills to take than before!”
