Serum folate?
Is serum folate the same as ferritin?
A friend got turned down for an elective procedure because her 'ferritin was 19 and borderline'
I've just looked at my bloodtest from 2023 (I was put on folic acid)
And it was mine was <2
But can that be the same thing as it say normal range is 3.9- 20
And she was told 19 was 'borderline low'
Surely 19 would be near the top end of healthy?
