SYDJD ... I completely agree with all the advice you have received. Not sure why your doctor made mention of your B12 being elevated (according to the "normal" range) in the first place. All of your B vitamins are water soluble. This basically means that your body will not hold on to the vitamin unless it is used. The unnecessary vitamin remaining in your body will be excreted in your urine. As stated above, there are instances where a person's kidneys are not filtering properly & may cause an abundance of a multitude of substances. That being stated, the BUN & Creatine levels would have been out of the normal range indicating your kidneys are not functioning properly. According to your blood tests, you show absolutely no indication your kidneys are not working properly; thus, your body is in balance. Your body likely requires more B12 than the average person. This could be temporary or permanent. You may want to increase your water intake, being sure you are taking in enough fluids, so that the unused B12 is properly excreted along w/all other waste. Rest assured, your B12 being "elevated" is not a diagnosis, condition, or disease. The "normal" range is not an absolute, particularly when regarding the measurement of B12. Good luck & keep us posted on any new information you receive. ~ Stacy
