Iodine Blood Test
The iodine test is a blood test that checks the iodine level and helps screen for iodine deficiency. Iodine is an essential element that is required for thyroid hormone production of thyroxine (T4) and triiodothyronine (T3). Thyroid hormones help regulate important biochemical reactions, such as protein synthesis and are very critical in metabolic activity. There are several types of food that are good sources of iodine including fish, other types of seafood and eggs. Table salt also has iodine added to it.
There might be certain groups of people that are at risk of iodine inadequacies, such as people who do not use iodized salt or those living in a region with low iodine sources, pregnant women, vegans or people who eat few to no dairy products, seafood, and eggs.
