From the field
The same lessons come up again and again from people actually doing the job:
People don't realise that a huge share of medical decisions rely on lab tests — and we run them. We're the unseen science behind diagnosis. A doctor can't treat what they can't diagnose, and that diagnosis often starts in our lab.
