Andy,
My tests/reports rarely make sense. I tested b12 and Vit D few years back, but it was too high. Vit D showed above 100, toxic levels. Which i doubt is true.
Same happens with my iron tests, its either overloading or too low. Like everything seems to float in my system without getting used. Nowadays I can never reach hb 10+, i'm stuck at levels below 9.5. Sometimes as low as 8.
I still take a calc, D, mg supplement, and a multi with low iron. But i'm still ghostly pale.
