SphingoTec launches point-of-care test for bio-ADM, a biomarker for life threatening endothelial dysfunction
- Endothelial dysfunction is driving pathophysiological processes such as congestion in heart failure, shock in sepsis, and lung dysfunction in COVID-19
- Bioactive Adrenomedullin (bio-ADM®) is a proprietary biomarker for real-time assessment of endothelial function in acute and critical care settings.
- High blood levels of bio-ADM® have been shown to predict septic shock, to diagnose residual congestion in heart failure, and the need for organ support in critically ill patients, including COVID-19
- IB10 sphingotest® bio-ADM® runs on SphingoTec`s automated Nexus IB10 point-of-care platform and quantitatively measures levels of bio-ADM® directly in blood samples
Hennigsdorf/Berlin, Germany, July 22, 2020
– Diagnostics company SphingoTec GmbH (“SphingoTec”) today announced the launch of its IB10 sphingotest® bio-ADM®, a CE-IVD-marked point-of-care test to quantitatively determine blood levels of Bioactive Adrenomedullin (bio-ADM®). Blood levels of bio-ADM® reflect in real-time the functional status of the endothelium, the inner cell sheet of blood vessels. The test is made available on the company`s rapid point-of-care platform Nexus IB10 that uses whole blood samples without any pre-processing, requires less than three minutes hands-on-time, and delivers results after 20 minutes. Nexus IB10 can be flexibly deployed in laboratories or near-patient settings such as intensive care units (ICUs) and Emergency Departments (EDs).
In numerous studies on more than 22,000 patients admitted to ICUs and EDs, bio-ADM® has been shown to predict distortions of the inner cell sheet of blood vessels, the endothelium (1). Failure of the endothelial function has been demonstrated to precede edema and the life-threatening blood pressure drop that causes shock and multiorgan failure e.g. in patients with sepsis at ICUs and EDs (2-3). In heart failure patients, bio-ADM® blood-levels reliably and objectively reflect tissue congestion and residual congestion (4). Recent data show that elevated blood levels of this functional biomarker also identifies patients in the general ICU patient population who require immediate life-saving therapeutic interventions (5). In ICU patients with severe COVID-19, endothelial dysfunction has been identified to play a crucial role in the disease progression, thus providing a rationale to monitor bio-ADM® to guide the therapy stabilizing the endothelium (6).
Dr. Andreas Bergmann, CEO and founder of SphingoTec commented: “The endothelial function plays a key role in a large number of critical care conditions, such as sepsis, septic shock, acute heart failure, and COVID-19. A distortion in the endothelial function predicts the patient’s progression to a critical stage. Therefore, bio-ADM® screening can identify high-risk patients who require early life-saving therapeutic intervention. With the launch of this rapid test for bio-ADM® on our widely established Nexus IB10 immunoassay platform, we aim to support earlier treatment decisions and improve outcomes of acute care patients.”
The IB10 sphingotest® bio-ADM® assay is commercialized in Europe and other regions that accept CE-IVD certification through SphingoTec’s network of distribution partners for the Nexus IB10 platform, together with a broad menu of standard tests for acute and critical care.

About bio-ADM®
sphingotest® bio-ADM® measures blood levels of bioactive adrenomedullin (bio-ADM®), a hormone maintaining endothelial function. The endothelium contributes to blood pressure and separates blood from the surrounding tissue. Elevated blood levels of bio-ADM® predict blood pressure break down and leaky vessels resulting in oedema. Imbalanced endothelial function is the major cause of shock ultimately resulting in organ dysfunction and death. Early identification of an imbalance in endothelial function allows guidance of vasopressor and diuretic therapy in critically ill patients to improve outcomes.

• PenKid surpasses serum creatinine on Day 1 post-transplant in detecting delayed graft function (DGF), with an AUROC of 0.87 versus 0.56 for creatinine. • PenKid differentiates slow graft function (SGF) from DGF up to 8 days earlier than current methods, supporting more timely clinical decisions. • PenKid levels remain unaffected by kidney replacement therapy (KRT), allowing for more accurate assessment of kidney function. • Independent validation in transplant cohort from Australia confirms performance and broad applicability. Hennigsdorf/Berlin, Germany, July 1, 2025 - Diagnostic company SphingoTec GmbH (“SphingoTec”) announces a landmark study (1) published in Transplant International, led by Heidelberg University Hospital in Germany in collaboration with researchers from Sydney, Australia, which identifies Proenkephalin A 119-159 (penKid) as a reliable biomarker for early and precise assessment of graft function trajectories following kidney transplantation. The research demonstrates that PenKid not only identifies patients at risk for DGF significantly earlier than traditional markers but also distinguishes between slow and delayed graft function with remarkable accuracy, offering clinicians a valuable new tool for patient management. The study prospectively evaluated 159 consecutive kidney transplant recipients at Heidelberg University Hospital and validated findings in an independent cohort from Sydney. PenKid consistently outperformed serum creatinine (SCr) in predicting graft function trajectories, particularly in the critical early post-transplant period. Notably, PenKid’s ability to remain unaffected by KRT—a treatment for severe kidney dysfunction—further sets it apart from SCr, which can be influenced by non-renal factors and KRT itself, thereby enhancing the reliability of graft function assessment. Multivariate analysis confirmed PenKid as the strongest independent predictor of both short-term graft function and 30-day outcomes, underscoring its clinical utility for early risk stratification. The biomarker’s superior granularity allows for nuanced classification of DGF severity, supporting more informed decisions regarding the initiation of dialysis or biopsy and offering potential for individualized patient care. With these findings, penKid steps forward as a practical addition to the transplant clinician’s toolkit, promising to sharpen decision-making for optimal outcomes. Its adoption could help transplant teams act with greater confidence and precision, ultimately strengthening the standard of care in kidney transplantation. ## References 1. Benning L et al.

Unlike traditional markers such as serum creatinine, penKid levels are not influenced by inflammation or other confounding factors like age or sex (1,2,3). Studies have shown that penKid allows earlier detection of acute kidney injury (AKI), predicting changes in serum creatinine up to 48 hours before conventional diagnostic criteria are met (1,3). This early detection capability is particularly valuable in critically ill patients, including those with sepsis or septic shock (1,3,4). Additionally, penKid has shown potential for monitoring renal recovery under dialysis and could help predict successful weaning from renal replacement therapy (5,6). ## References 1.
