Four perchlorates are of primary commercial interest: ammonium perchlorate (NH 4 ClO 4), perchloric acid (HClO 4), potassium perchlorate (KClO 4), and sodium perchlorate (NaClO 4). Perchlorate is the anion resulting from the dissociation of perchloric acid and its salts upon their dissolution in water.Except for potassium perchlorate, perchlorate salts are soluble in water and dissociate into the perchlorate anion and the cation from the salt.n the U.S., perchlorate has been found in the water resources of several western states, including Lake Mead and the Colorado River, ranging from 4 to16 Î¼g/L.
Thyroid-Stimulating Hormone (TSH). Guide. A thyroid-stimulating hormone (TSH) blood test is used to check for thyroid gland problems. TSH is produced when the hypothalamus releases a substance called thyrotropin-releasing hormone (TRH). TRH then triggers the pituitary gland to release TSH.TSH causes the thyroid gland to make two hormones: triiodothyronine (T3) and thyroxine (T4). T3 and T4 help control your body's metabolism.Triiodothyronine (T3) and thyroxine (T4) are needed for normal growth of the brain, especially during the first 3 years of life.ow To Prepare. Tell your doctor if you have had any tests in which you were given radioactive materials or had X-rays that used iodine dye within the last 4 to 6 weeks. Your test results may not be correct if you have had iodine contrast material before having a thyroid-stimulating hormone (TSH) test. 1 | 2 | 3 | 4.
