I stay in Poland currently do some personal work. I did my blood test last week Iron-88.0 ug/DL Ferretin-2.52 ng/ml (last year it was 12,and doctor told me it's normal) Vit D- 22.80 ng/ml TSH-3.9390 uIU/ml Vit B12-363.00 of/ml (I was taking B complex ,so I need to test it again without supplements as I was low in my last year test) Folic acid-15.60 ng/ml I am confused with my ferretin level and Iron level. I am having joint pain, severe hairfall,grey hair , shorting of breath and what not.
