These doctors perform unnecessary tests. The yre told they need to generate money for these hospitals to stay atop. Most doctors cant even read these results that are generated. My niece was given a diagnosis for sepsis, but being a medical personnel i decided to look closer. Only to find she had a urinary tract infection. They made her stay in hospital for three days for a damn UTI!!! This is something you get antibiotics and then keep up with your routine.
Docs depend too much on machines instead of good old detective work, and these machines are expensive.
