Artificial intelligence system can guess your age from a blood sample

While most of us know how old we are from our birthday, there are some - like those who are orphaned at a young age - who have no idea when they were born. But now a new technique may make it possible to determine a person's age with a simple blood test. A team from Insilico Medicine in Baltimore, USA, have used artificial intelligence to create programmes that can predict a person's age from chemicals in their blood. In research published in the journal Aging, they explain how deep learning algorithms have allowed them to estimate someones age within a 10 year time frame with 83.5 per cent accuracy. By looking at biomarkers in the blood, such as glucose, urea, red blood cell count and the protein albumin, the Deep Neural Network was able to work out the age of who it came from.
