About Us


The scientific idea behind the product of Loop Diagnostics emerged during Enrique Hernández’s (CEO) postdoctoral studies at Bellvitge Hospital in Barcelona, where he investigated the immune response in different diseases, including sepsis. During his research, Hernández recognized the importance of analyzing the state of the immune system to detect the presence of sepsis early and accurately.

Quality Policy

Loop Diagnostics is dedicated to delivering exceptional products and services that consistently surpass our customers’ expectations. We are committed to adhering to the highest standards and complying with all relevant regulations, ensuring the utmost satisfaction of our valued customers and stakeholders.

Loop Diagnostics SL has established, documented and implemented a Quality Management System (QMS) following the ISO 13485 standard.

Traditionally, sepsis detection relied on clinical signs and symptoms, often manifesting when the disease had already progressed significantly. Hernández realized that the immune system plays a crucial role in the body’s response to sepsis and that changes in gene expression and immunological profiles could provide crucial information for early detection of the disease.

Moreover, during his studies, Hernández delved into the concept of endotoxin tolerance in the innate immune system. He discovered that the innate immune system can become “tolerant” to endotoxins after prolonged or repeated exposure to them. This endotoxin tolerance can hinder early sepsis detection, as the immune system may not mount an adequate inflammatory response in the presence of endotoxins. 

Understanding the scientific basis of endotoxin tolerance, Hernández developed the technology of Loop Diagnostics to analyze and evaluate changes in gene expression and immunological profiles related to sepsis and endotoxin tolerance. This innovative approach enables the early and accurate detection of sepsis, even in situations where the immune system may be “tolerant” to endotoxins. 

By incorporating research on endotoxin tolerance into Loop Diagnostics’ approach, significant progress has been made in the field of early sepsis diagnosis. It provides physicians with a more precise and effective tool to identify the disease in its early stages and take timely action for appropriate treatment.


Enrique Hernandez, PhD

Chief Executive Officer (CEO)

Born in Soria in 1989, he moved to Lleida to pursue a Biotechnology degree. His scientific interest was sparked during an internship in the United States. He participated in an Erasmus study program in Florence, specializing in the biomedical field. He completed his PhD at La Paz Hospital in Madrid, focusing on reprogramming the immune response in infectious diseases like sepsis. During this time, he published over 25 papers in less than 5 years, including notable works such as ERJ 2017 (first author), JCI 2016 (second author), and JID 2017 (last author). Recently, he completed the d•HEALTH Barcelona program, which provided an excellent opportunity to apply his biomedical knowledge to create real societal value through a business model. Currently, he serves as a post-doctoral entrepreneur in the Innate Immunity and Pathology of the Critical Patient group under Joan Sabater, while also managing Loop Diagnostics S.L., an innovative microbiological diagnostic startup, as its CEO.
