Hi Ebs. Do you get T4 or Free T4? FT4 is more accurate. And what ranges are given for the TSH? While some labs give different ranges for the T's, the TSH range is fairly consistent, and the American Academy of Clinical Endocrinologists has revised the ranges. You can check it out at www.aace.org . Is the upper range for TSH on your labs closer to 3 (the new upper range) or 5 (the old range)?
