John Midgley obituary

My colleague and friend John Midgley, who has died aged 88, was a scientist, biochemist and researcher best known for the invention and development of thyroid hormone blood tests in the 1980s.

A pioneer in medical biochemistry, his work in the field of thyroid hormone detection hugely improved patient care. John was also a passionate advocate for patients - as a medical adviser to the charity Thyroid UK, commentator and writer.
