Hi, just received my test results. I'm a little bit confused, my vitamin D is low at 21 µg/L (norm: 20-40) while my 1, 25 Di-OH vitamin D is high at 66 pg/mL (norm: 25-66). Does anyone have an explanation for it? Other results were: Insulin Growth Factor I: 134 µg/L (norm 116-358) IGFBP3: 2530 µg/L (norm 3360-7810) Parvovirus B19 AL IgG 4.2 (> 1.1 positive) Eosinophiles: 12 % (norm 0-4%) Testosterone at 3,57 µg/L (norm 3-10) TSH 1,95 mU/L (norm 0.27-4.2) FT3 2,69 ng/L (norm 2-4.4) IgE Total 4000 kU/L (norm 0-120) HHV-6: active infection (before that I had a HHV-7 infection which is now negative. test method was nested PCR) So for me it seems that I'm running out of hormones, I'm having a strong Th2 shift and I have some reactivated viruses. Any comments, input on the insulin growth factor? Would it be wise to substitute testosterone?
