Can doctors test for vitamin deficiency with a finger prick?I've been tired and sick more than usual this winter. There are several vitamins and minerals that I may or may not be missing out on: iron (I've had problems with this in the past), B12 (I don't always eat enough meat) or vitamin D (it's my first Seattle winter). I don't know which, if any, of these I'm not getting enough of. The supplements I looked at seemed to have really high doses. I did some research and ended up even more confused. I'd love to talk to a doctor about this, but I have a really hard time with blood tests. Would a finger prick be enough to test for these three things? Are all doctors willing to do finger pricks on adults? My last doctor refused to do finger pricks, but before that I had a pediatrician who did them all the time. |
