MM Kaplan, PR Larsen, FR Crantz, VJ Dzau… - The American Journal of …, 1982 - Elsevier
We measured serum total and free thyroxine (T 4) and triiodothyronine (T 3) concentrations,
free T 4 and T 3 indexes, thyroid-stimulating hormone (TSH), thyroxine-binding globulin
(TBG) and thyroxinebinding prealbumin (TBPA) concentrations in 98 patients hospitalized
for acute medical illnesses. The free thyroxine index (FT 4 I) or TSH level was abnormal in
16 percent, but only 3 percent had thyroid disease. Serum free T 4 measurements by
equilibrium dialysis were abnormal in 25 percent, but no additional patients who initially had …
