I don't understand folate results

[Mouse]

I have just had my latest blood test results and the serum folate range is >4.00 U.

My results are >20.0 ug/L. Does that mean that my folate is very high?

If so does it matter?

My B12 is 448 (180-1000). I know the two are connected in some way but I can't find enough information to understand if my folate level is an indication of something or if it is normal.

I am hoping that someone on this forum with have the answer.
