Not exactly sure. I applied for an apt at Mayo Gastroentrology. Had to send a packet with records, tests, procedures, etc. They told me upfront they only accept a small number of patients from hundreds seeking apts. I’m not too optimistic. I applied there once before for migraines. They refused because they said I had already tried everything they had to offer. Hard to believe because “I” eventually did figure it out on my own. Success rates are a big deal to donors. But I’m desperate at this point.
