I am about to go for another blood test, since the lab refused T3 test last time, I intend to pay privately for this, but I need to know which to ask for.
GP can do TSH and T4, but wondering which private test to go for, my choices are:
T3
Or
FreeT3
Or do I need to spend more money and get all the following:
Thyroid Function: TSH, FT4, TT4, FT3, TGAb, TPOAb
Vitamins: Vitamin B12 (active), Folate, Vitamin D
Inflammation Marker: CRP-hs
Iron Status: Ferritin
???
Background: Since my last blood test 7 weeks ago I have been taking 50mg Eltroxin and supplementing with 3000mg daily Vit D, (this is in addition to the monthly Vit D supplement tablet prescribed by the gp, which would not have been equivalent to a loading dose that I need). I still don’t feel well, fatigue being the worst symptom.
My last results while taking 25mg Eltroxin were:
Free T4 12.2 (10.50-22.00)
T3 lab refused to analyze
TSH 3.67 (0.27-4.20)
Serum vit B12. 399 (188-883)
Serum Folate 8.7 (3.00-17.00)
Serum Ferritin 19.0 (10.00-200.00)
Iron 18 (9.00-30.00)
Transferrin 2.5 (2.00-3.60)
Calculated TIBC 63 (53.00-95.00)
Transferrin Sat. 29 (19.00-43.00)
***Vitamin D 28 ( deficiency <50, Insufficient 50-75, Adequate >75)
Same lab, with same ranges previous results when unmedicated:
August 2017:
Free T4 12.9 (10.50-22.00)
***TSH 4.22 (0.27 - 4.20)
IgG 12.10
IgA 1.69
IgM 1.61
Serum electrophoresis NOMB
***Anti TPO abs 74 [H]
IgA anti tTG <1
Anti ENA screen 0.2
Anti Nuclear Antibodies NEG
July 2017
:
Free T4 12.6
***TSH 6.25 [H]
Feb 2013
Serum vit B12 446
Serum Folate 15.9
Serum ferritin 26.5
Advice on which blood tests to request would be helpful. Thank you.
