Normal lab values for TSH are between 0.5-6 uU/ml. The Free Thyroxine,(FT4), levels can vary from 0.7-1.9 ng/dl. Your T3 results should range from 80-180 ng/dl, and Radioactive Iodine-123 uptake, (RAIU), 10-30%. If test results appear normal, yet suspicious symptoms remain, some physicians will prescribe further testing. Some doctors will try thyroid medicine to assess effectiveness and relief.
