Mortality in sepsis is very high in critical-care patients and the major reason for this is delay in pathogen diagnosis. Every hour of delay decreases the survival by 8 to 10 % and this is where our technology and device adds value. Our device helps in not only rapid diagnosis of bacterial bloodstream infections very early into the infection but can also assess indirectly the severity of infection by correlating to the biomarker concentration. It also gives Gram status of the bacterial infection within a few minutes, improving evidence-based therapeutic decision time and monitoring of treatment response. The low-cost of the device also makes it more accessible to low and middle income groups, thereby having a dramatic and positive impact on the outcome of sepsis management in intensive care units around the globe. It is also hoped that use of our devices would help to reduce development of antibiotic resistance. All the technologies currently available require time for growth in culture and detection by sophisticated technologies which involve expensive laboratory based instruments and protracted time to diagnosis. Our devices are simple to use and can be operated by a semi-skilled worker. The results are also fairly easy to interpret. This is done using a colour chart (shown below on the left) and matching its colour band with the spot intensity obtained on the device after running the assay (shown below on right). The spot’s colour intensity correlates to the severity of infection.
