I know we are always discussing vitamins - and that they are important.... and I know many you get tested for specific ones..... if your basic blood counts are normal - how does one get the doctor to test for vitamin deficencies? I have the Liza Jane sheets - but again, the doc wants to be the leader.... are there signals in our basic bloodwork that would trigger a doctor to test for a specific vitamin deficiency? Or something the we can say as a patient to request specific imporant tests for those of use with PN - auto-immune issues, etc. based on a certain symtom that we might not think signifiicant to mention? (I know they tested me for B12 a few times over the years because of its relationship to PN) but thats about it as a specific entity.....?
