Hi Birgitta-A,
FYI. I found some info from the below web site for both of the reference range but again it might be different for different lab.

Serum vitamin B12 ---> The most widely used test for B12 deficiency is the serum B12assay (reference range 150-600 pmol/L).
Serum folate ---> The usual first test for folate deficiency is assay of serum folate (reference range 7-40 nmol/L*).
* Reference ranges for serum folate, red cell folate and serum vitamin B12 are specific to the methodology used by individual laboratories and may not be identical to the
ranges given in the text.
My sister consulted a doctor, according to the doctor, both of the results showing a little bit high reading, stopped the Vit-B12 and Folate for few weeks and monitor.
