I've got a printout of my latest blood tests done at the end of May. I know the ferritin is low, but I'm wondering if the folate, zinc, and vitamin D could be better?
Serum folate 7.9ug/l [2.1 - 14.0]
Zinc 10.1 umol/l [10.0-18.0] I don't think I have any signs of zinc deficiency
Vitamin D 86nmol/l [<25 deficient, 25-50 insufficient, >50 adequate]
Is 50 adequate? I've been supplementing for about 18 months, was previously 20 I think.
There are different ranges for ferritin depending on age and gender which I didn't know:
Serum ferritin 37ug/l [female >45 years (that's me) 24-155] [female <45 years 10-65] ??
Seems like such a big difference. I've been taking ferrous fumarate, about 4 weeks now.
FBCs etc all reasonably good and B12 1102 (180-900)
Nov 12: FT4 20.3 (9-24) TT3 1.4 (0.9-2.8) TSH 0.03 (0.35-5.5) 175ug
Jan 13: FT4 24.2 TT3 1.7 TSH <0.01 on 200ug
Mar 13 FT4 25.9 TT3 1.6 TSH 0.01 on 175/200ug alt days
May 13 FT4 21.2 TT3 1.4 TSH <0.01 on 175ug
To me these aren't really logical! They were all taken between 9 and 10.00am.
I'm now back on 175/200ug alt days. I had a couple of busy days Fri and Sat and since Friday night have been feeling awful - I actually feel as bad now as I have ever felt, before or since diagnosis. I know it could be a bug - doc would probably say it's 'a virus' - but it feels so like I'm back where I started.
