A blood test Nlovember 4, 2019 showed:
TSH 0.4-4.50 miU/L 0.54L
TT4 4.9-10.5 mcg/dL 3.8L
FT4 0.8-1.8 ng/dL 0.4L
FT3 2.3-4.2 pg/mL 3.4
TT3 76-181 ng/dL 119
Urinalysis was within range
Cholesterol <200 mg/dL 135
Complete Metabolic Panel was all well within range.
I can't figure out why my T4's are low but everything else is good?
Blood test on 1/6/2020 TSH 0.4-4.50 miU/L 0.26L
TT4 4.9-10.5 mcg/dL 5.8mcg/dL
FT4 0.8-1.8 ng/dL 0.8 ng/dL
TT3 76-181 ng/dL 127ng/dL
FT3 2.3-4.2 pg/mL 3.2pg/mL
My T4's are better but still low: My change in dose was from 50 mcg T4 to 75 mcg T4
and 30 mcgT3 to 20 mcg T3 I feel like I need more T3 and so I added 5 more to make it 25 mcg T3. I believe I was under-dosed for 28 years. The GP who started me began at 88mcg T4-only & never changed for 28 years. The last almost 2 years I have gotten an endo and am still tweeking. Any thoughts? I feel really great except for a stiff neck that creaks when I turn it and, occasionally, still, cold hands & feet but then, I'm 74 years old. I know the low T4's mean something, esp. the FT4? Anybody had anything similar?
