Protein Bound Iodine - an overview ScienceDirect Topics
WebbINTRODUCTION Measurement of the serum protein-bound iodine (PBI) is a valuable index of thyroid function. However, many radiological contrast media contain high concen- trations of iodinated organic compounds and, following the use of these substances, falsely elevated PBI levels are found which persist for weeks, months, or even years … Webb11 jan. 2024 · Iodine is a trace element found in some foods and fortified salts. According to the National Institutes of Health (NIH), it's an essential part of the thyroid hormones thyroxine and triiodothyronine, which regulate vital processes such as protein synthesis and the development of the skeletal system. Iodine also helps the immune system. WebbOver 99 percent of each hormone is bound to one of three proteins—thyroxine-binding globulin, transthyretin (also known as thyroxine-binding prealbumin), and albumin. Serum thyroxine (and triiodothyronine) can be measured as the total hormone, which includes the bound and free fractions, or as free hormone alone. margaret louise newhall
