What does our urine tell us?

By collecting urine for an entire day and night and investigating it, a lot can be discovered about someone’s physical fitness and lifestyle, Professor Gerjan Navis of the UMCG says. Vulnerable people can be identified early on: they have too little creatinine in their urine. Creatinine is a good predictor of someone’s fitness and chances of dying. Urine thus shows whether something needs to change, and if so what. Participants in Lifelines, the large-scale research project on healthy ageing, are already collecting 24-hour urine samples.

The weekly online video magazine Unifocus highlights topics related to the University of Groningen in the fields of research and society, student life, teaching, policy and internationalization.
