SphingoTec's endothelial function biomarker bio-ADM® improves risk stratification of sepsis patients at ICUs
- New study data show that monitoring blood levels of sphingotec’s endothelial function biomarker bio-ADM® on top of guideline parameter lactate improves risk stratification of sepsis patients admitted to intensive care units
- Monitoring of both, lactate and bio-ADM®, in sepsis patients allows early identification of patients that require immediate intervention at admission to the ICU.
- Sphingotec is set to launch a point-of-care bio-ADM® assay running on its proprietary automated Nexus IB10 instrument in mid-2020.
Hennigsdorf/Berlin, Germany, March 5, 2020 -
Diagnostics company SphingoTec GmbH ("sphingotec", Hennigsdorf Germany) today reported on new data on the utility of endothelial function biomarker bioactive Adrenomedullin (bio-ADM®). The data show that bio-ADM® allows identification of sepsis patients who are at high risk of fatal outcomes despite low or decreasing levels of the routinely monitored parameter lactate. Lactate, a parameter that identifies reduced blood oxygenation of tissue, is routinely used as a reference in the diagnosis of septic shock. However, lactate is rather unspecific to sepsis and insensitive. This limitation can be overcome by monitoring, in addition to lactate, the blood levels of bio-ADM®, a biomarker that can reliably detect blood vessel leakage, one of the main causes of septic shock.
According to recent findings published in Critical Care[1], data from over 500 sepsis patients enrolled in the AdrenOSS-1 study demonstrate the added value of bio-ADM® to lactate monitoring. The AdrenOSS-1 study investigators could show that even though normalizing lactate levels indicate a significantly decreased risk of mortality, an additional measurement of bio-ADM® blood levels can help identify those patients that are still at risk of fatal outcomes despite their lower lactate levels. Among septic patients with decreasing lactate, high bio-ADM® levels identified patients who had a 4-time higher mortality risk than patients with low bio-ADM levels. According to the authors of the study, measurement of bio-ADM® on top of lactate may help refine risk stratification and thus guide resuscitation during sepsis.
Lactate has been used for more than 30 years to monitor organ hypoperfusion in sepsis patients. However, lactate blood levels are influenced by many other physiological and pathological processes. Clinical data from more than 22,000 patients demonstrate that high bio-ADM® levels independently from inflammation and co-morbidities indicate distortions in the barrier function of the inner cell sheet of blood vessels, the endothelium. Loss of this barrier function is considered a key driver in the development of hypotension and eventually septic shock with loss of organ perfusion in sepsis patients[2]. According to sphingotec’s research, bio-ADM® can explain about 60% of the fatal outcomes in sepsis.
“Our biomarker bio-ADM® can reliably support acute care physicians in identifying high-risk sepsis patients” said Dr. Andreas Bergmann, founder and CEO of sphingotec. “We are set to launch the fully automated CE-IVD-marked point-of-care bio-ADM® assay on our widely established Nexus IB10 immunoassay instrument by mid-2020. We are convinced that this rapid test for bio-ADM® will support earlier treatment decisions and thereby will assist clinical decisions that may improve the outcomes of patients at ICUs and emergency departments.”

• New ELISA sphingotest® penKid® enables widespread measurement of the kidney function biomarker Proenkephalin 119-159 (penKid) using standard laboratory equipment. • Only available test to match SphingoTec’s reference chemiluminescence assay, developed with patented high-sensitivity technology to provide consistent results across platforms. Hennigsdorf/Berlin, Germany, April 28 2026 - SphingoTec GmbH announces the launch of the ELISA sphingotest® penKid®, a new assay designed to make testing of its proprietary biomarker broadly accessible to research laboratories and pharmaceutical partners. Providing ease-of-use and precision, the test facilitates large-scale investigations of human kidney function in both acute and broader clinical research contexts. Responding to growing research interest The launch follows increasing demand from the scientific community to study penKid - a biomarker reflecting the current state of kidney function in critical care environments. While SphingoTec’s high-sensitivity sphingotest® penKid® assay serves as the reference method for clinical research and third-party IVD assays, the assay technology requiring dedicated equipment was not easily adoptable in research laboratories. The new ELISA sphingotest® penKid® now allows researchers worldwide to benefit from SphingoTec’s patented detection technology using standard photometers, extending penKid testing capability to a wider range of laboratories. Proven performance and data continuity The ELISA sphingotest® penKid® has been developed to achieve excellent correlation with SphingoTec’s reference chemiluminescence assay, ensuring consistent, high-quality results across different assay platforms. Both methods share the same underlying technology capable of detecting penKid concentrations in the picomolar range. Thanks to this technology transfer, researchers can rely on the same analytical precision and reliability that supported the clinical studies establishing penKid as a valuable kidney function biomarker. The assay’s robust design and German manufacturing ensure durable consistency and reproducibility. With this research-use ELISA, SphingoTec responds to the increasing availability of non-validated assays and encourages researchers to not compromise assay quality and performance to ensure trustworthy results - since data from non-validated tests may reflect assay limitations rather than the true performance of the penKid biomarker. Complementary approaches for clinical use and scientific exploration SphingoTec pursues its commercial strategy for the biomarker penKid through strategic out-licensing partnerships such as Boditech Med, which has developed an IVDR-certified assay for routine clinical use and rapid diagnostics. The newly launched ELISA sphingotest® penKid® represents a complementary initiative, specifically designed to support high-throughput clinical and translational research. Through this dual approach, SphingoTec reaffirms its commitment to fostering scientific collaboration and promoting the broader exploration of penKid across diverse research settings. “Developing the ELISA sphingotest® penKid® reflects our long-term commitment to improving critical care diagnostics,” said Deborah Bergmann, Managing Director and CEO of SphingoTec GmbH. “Beyond its currently validated clinical applications, we see strong potential for penKid to support research and improve diagnostics in other fields where kidney function is relevant. By encouraging scientists worldwide to incorporate penKid into their studies and clinical programs, we aim to accelerate innovation and advance best-fit diagnostic solutions that ultimately improve patient care.” About SphingoTec SphingoTec GmbH ("SphingoTec"; Hennigsdorf near Berlin, Germany) is a biomarker company focusing on the out-licensing of innovative critical care solutions for diagnosing, predicting, and monitoring acute medical conditions.
