Did you know that one of the earliest uses of biomarkers to gauge the failure of a biological processes in the body was 2500 years ago by Hindu doctors? The physicians would test the sugar levels of patient’s urine by seeing whether or not ants were attracted to it. If ants were attracted by the presence of sugars, the conclusion was that the patient had diabetes.
Fortunately we’ve moved beyond the need for ants in the doctors surgery. This video, part of Roche’s ‘Drawn to Science’ series, explains a little more about the history of biomarkers, and their modern uses and incarnations.
