Active b12 test question:
I just got an active b12 result of 234 and the range is 25-165. I've taken b12 supplements sporadically over the past few years. I had been off them but took a few days worth this week. It was a test I not been planning to take and I know now it might have been altered by the supplements. My question is, could it have been altered by that much? To me, the number seems alarmingly high. I'm a 29 year old with CBC,renal and liver panels all done a year ago and all within healthy ranges. No symptoms, just confused!
