A new blood test has been developed that can detect with remarkable accuracy whether an individual has not slept for 24 hours. This innovative blood test, described in a publication in Science Advances, utilizes a combination of biomarkers found in the blood, achieving a 99% probability of correctly identifying sleep deprivation when compared to a well-rested state. This discovery holds significant implications for enhancing safety in critical situations, where sleep deprivation greatly increases the risk of accidents and injuries. The motivation behind this research stems from the global conc…
