Thanks for your message re. the Vit B12. As my B12 level was tested with pmol/L unit of measurement it may not be as bad as you assume based on what you are used to. Pmol/L is a SI (Systeme Internationale) system of measurement which much of the world uses. If you use pg/ml then that is called CU's (Conventional Units).

The conversion factor for B12 is: 0.738 so
- to convert from the conventional unit to the SI unit, multiply by the conversion factor;
- to convert from the SI unit to the conventional unit, divide by the conversion factor.

Therefore my B12 level of 267 pmol/L (SI) converted to CU's; I need to divide 267 by 0.738 which gives me 361 pg/ml. Does that sound better? I know it is still not as much as in Europe and Japan where it is purportedly said that they use a 550pg/ml equivalent cut off (if I am correct).

Any feedback on 361pg/ml would be appreciated!!!
