Every day there are new advancements and breakthroughs in the medical sector and of late there has been another breakthrough in the medical fraternity. This new development is that of a blood test which can test liver damage within an hour. This new test can detect liver damage even before the symptoms start appearing and the credit goes to a team from the UCL and Massachusetts University. This test can address the need for early detection of liver disease. The desk and detect liver fibrosis which is the first stage of liver scarring which ultimately leads to fatty liver disease if left untreated.

Premature death due to liver disease is the third biggest cause of death in the UK and one of the leading causes of death worldwide. The main issue with liver disease that it goes unnoticed until it is detected at very late stages of the disease when the damage is done and very complicated to treat and in some cases the damage is irreversible even. In the Western countries, almost half the population have the risk of getting liver disease underground of obesity and due to heavy drinking habits. This test can be used on a routine basis at Hospitals and Clinics in order to screen people who are at an elevated risk of acquiring liver disease but are showing no signs of liver damage.

By designing a sensor which makes use of large molecules called polymers which are coated with flowers and dies so as to bind the proteins of blood based on their chemical properties, which then changes its brightness and color and gives a different pattern of fluorescence depending upon the protein composition of the blood sample, researchers at the University of Massachusetts have successfully designed and tested this sensor which is used for testing liver disease in humans. The sensing ability which is used in this testing makes use of a signature-based approach and is extremely versatile meaning that it is not disease-specific and can we apply to a spectrum of conditions. This opens new possibilities of diagnostic systems which can track health status and monitor wellness.
