I had a recent blood test which showed my folate level to be 9.1. I didnt get any ranges from the surgery but when I phoned them yesterday they said that my level needed to be above 3.8. My friend who is a nurse in the same area where I live gave me a range of 4.5-45.3 nm0l/l. I am already anaemic and on iron ferrous sulphate 200 twice a day (I was taking them 3 x daily). I just wondered if I should be taking folic acid. I already take ones which I buy online but should I be prescribed them. I feel very tired all the time and am trying to work out whats causing it. My thyroid bloods are ok TSH 0.01, T4 23.3, T3 5.7. So, I know it's not my thyroid. Although, have an endo appointment on friday. I was supposed to be moved onto NDT, however, the hospital sent the letter to a doctors in Hereford by mistake instead of my GP in Wales. I have never lived in Hereford nor had any appointments there so there was a mix up somewhere.
