A new device that detects sepsis using light can identify the deadly condition in less than thirty minutes.
On the average, sepsis kills about 20,000 people a year worldwide. To offer a quicker way to detect and treat the disease, the EU-funded RAIS consortium developed a device that relies on a small sample of the patient’s blood collected during the operation. That sample is separated to retrieve the plasma, which flows over a slide containing a microarray of antibodies. A pair of light beams are shown through the microarray, with one passing through a clear area of the slide to create a reference. By comparing the difference in light intensity, a signature pattern can be discerned that will indicate the presence of sepsis—allowing clinicians to start treatment early if necessary.
