FERRITIN 31 (30 - 400)
FOLATE 2.3 (2.5 - 19.5)
VITAMIN B12 206 (190 - 900)
VITAMIN D TOTAL 30.5 (25 - 50 deficiency)
Iron infusion done in 2016, was last on iron 4 years ago, waiting to start B12 injections hence why below range folate. Taking 800iu D3 since 2012, results done 3 months ago thanks for any advice
