My mum was speaking with a lady recently who has had her thyroid removed due to cancer. She had an awful time after getting her medication right. After 18 months, she was finally listened to and they did a diagnostic blood testing that looked at what was happening with her pituitary and adrenal glands that lasted the whole day. It was only after this that her medication was changed and she recovered. My mum didn't remember then name of this test. Does anyone know what it is?
