After another poster showed test results a little earlier, I realised the stark difference between regions on what is the recommended range for various samples.
In my area the range for B12 is 180-914
The range for Folate is 3.1-20
Not that serum B12 is that accurate, but I would be deficient with a reading of 170 but fine in another area.
Are there any significant anomalies in the range across the country, perhaps even the world?
I know the lower limit for B12 is higher in Japan and Canada.
