Hi all many thanks for all the help in the past which made me ask for the additional blood tests and to my doctors surprise I have a Vitamin D deficiency and that was very low.
I'm a bit concerned about some of the other low results (including TSH) and would welcome your feedback. Although my doctor did not seem to be that worried and has given me a course of Fultium-D3 four 800ui caps a day for 3 months. I'm also on 125mg of Levothyroxine for my underactive thyroid.
Vit D = 14 nmol/L (range 50.0 - 120.0)
free T4 = 19.9 pmol/L (12.0 - 22.0)
free triiofthyronine = 6.6 pmol/L (3.1 - 6.8)
TSH = 0.06 (0.27 - 4.2)
B12 = 296 ng/L (197.0 - 771.0)
Folate = 6.0 ug/L (> 3.9)
Ferritin = 35 ug/L (30.0 - 400.0)
Also had a Bone profile results all these within range low apart from the calcium ones. I'll post them if anyone is interested, but as I've not heard much about these tests I've left them off.
