I just received my 24 h urine results, on 8 grains of Erfa Thyroid daily (4 x 125 mg). Surprisingly enough, I felt hypoish on that dosage, but dismissed it, telling myself that was impossible. But my labs make me wonder...
T3 urine 24 h
0.98 ug/24 h (ref 0.4-2.20)
1.51 nmol/24 h (ref 0.61-3.38)
T4 urine 24 h
2.39 ug/24 h (ref 0.8-6.4)
3.08 nmol/24 h (ref 1.03-8.24)
To complete the picture, FTs in blood (24 hours after taking NDT):
FT3 3.5 (ref 1.7-3.7)
FT4 1.0 (ref 0.7-1.5) so not even mid-range
Does this mean that I was hypo on as much as 8 grains of Erfa daily? Most labs look lowish to me...
