Volition Announces Breakthrough Finger-Prick Detection of Nucleosomes; Expanding Global Market Potential for Sepsis Testing

HENDERSON, Nev., April 29, 2026 /PRNewswire/ -- VolitionRx Limited (NYSE AMERICAN: VNRX) ("Volition"), a multi-national epigenetics company, today announces a major technical milestone with the successful detection of nucleosomes in capillary blood from critically ill sepsis patients using its lateral flow prototype. This finger prick sample test could be used at the bedside, in the ER, or even at home in a self-test lateral flow kit, similar to COVID-19 or pregnancy testing, thereby greatly expanding the potential market beyond centralized lab testing.

Volition has previously announced results demonstrating correlation between whole venous blood (standard blood draw from the arm) samples utilizing its lateral flow prototype, and those of Volition's established automated Nu.Q® nucleosome assay performed in a central laboratory.

This study, part of the SUMMIT program, tested capillary blood samples from hospital patients in Intensive Care using a lateral flow finger-prick prototype and demonstrated the detection of nucleosomes in those samples. Results showed the feasibility of early detection of immune disruptions that can occur in a range of conditions including sepsis, simply and rapidly when using the test in a variety of settings (doctor's office, Emergency Department, Intensive Care Unit setting, or home self-test), without the need to send a blood sample to a hospital laboratory for testing.

Dr. Gaetan Michel, Chief Operating Officer, Volition said:

"This prototype technology has the exciting potential to strengthen our product portfolio by addressing critical unmet diagnostic needs with an accessible, cost-effective solution enabling rapid, minimally invasive, Point-Of-Care self- testing.

"By enabling decentralized testing, our total addressable market expands, and we plan to target NGO partnerships and strategic collaborations with companies active in low income countries to accelerate commercialization and market penetration.

"We are excited to announce this breakthrough and look forward to sharing full details of the study and commercial updates throughout the year."

Mr. Cameron Reynolds, Chief Executive Officer, Volition said:

"The ability to rapidly identify high-risk patients at the Point-of-Care by quantifying their nucleosome levels using a finger-prick sample and simple lateral flow device could enable quicker clinical decision making and consequently better patient outcomes.  

"We believe that this is a first-in-class breakthrough which positions Volition as a pioneer in capillary blood-based nucleosome diagnostics, unlocking a new and highly scalable, portable testing modality. To our knowledge, this is the first reported finger-prick lateral flow test to quantify nucleosomes, a marker of NETosis and diseases such as sepsis. Our aim going forward is to provide not just a positive-negative test, but also to give a quantitative readout to facilitate clinical decision-making on a low-cost platform suitable for widespread adoption around the world.

"With recent estimates indicating approximately 166 million cases of sepsis worldwide the addressable market is huge. All-cause sepsis related deaths in 2021 represented 31.5%¹ of total global deaths, with the highest burden of mortality in lower-middle-income countries."

"This is a potential gamechanger, not only in diseases where time is critical such as sepsis, but also in significantly expanding potential use cases beyond traditional hospital infrastructure.  It also creates a compelling pathway into underserved low-income countries, where laboratory infrastructure may be weak or non-existent."

About SUMMIT (Sepsis: addressing unmet needs for disease monitoring with a rapid test)

This innovative project, aimed at developing a capillary blood-based lateral flow test for the early diagnosis of sepsis, is carried out with the financial support of the Walloon Region.

About Lateral Flow Tests

The first commercial Lateral Flow Test (LFT), the Clearblue pregnancy test, was launched in the late 1980s. More recently, LFTs for COVID-19 virus were widely used during the COVID-19 pandemic. LFTs are designed rapidly to detect a molecule of interest in a simple test that can be conducted immediately on a patient's blood, urine or saliva sample in a doctor's office or even a home setting by a person with no scientific training and using no specialized equipment.

About Volition's Nu.Q® Nucleosome Assay

The Volition Nu.Q® nucleosome assay is a chemiluminescent immunoassay (ChLIA) that currently runs on the  Immunodiagnostic Systems (IDS) i10® automated analyzer platform. It holds a CE Mark to aid in the detection and evaluation of diseases associated with NETosis and is available in 27 European Countries.

About Volition

Volition is a multi-national company focused on advancing the science of epigenetics. Volition is dedicated to saving lives and improving outcomes for people and animals with life-altering diseases through earlier detection, as well as disease and treatment monitoring.

Through its subsidiaries, Volition is developing and commercializing simple, easy to use, cost-effective blood tests to help detect and monitor a range of diseases, including some cancers and diseases associated with NETosis, such as sepsis. Early detection and monitoring have the potential not only to prolong the life of patients, but also to improve their quality of life.

Volition's research and development activities are centered in Belgium, with an innovation laboratory and office in the U.S. and an office in London.
