Understanding Thyroid Problems -- Treatment\n\nWebMD Medical Reference \n\nThe Basics | Symptoms | Detection & Treatment\n\nHow Do I Know If I Have Them?\n\nA doctor can diagnose hyperthyroidism and hypothyroidism by testing the levels of thyroid hormones in your blood.  Doctors measure hormones secreted by the thyroid itself, as well as thyroid-stimulating hormone (TSH), a chemical released by the pituitary gland that triggers hormone production in the thyroid.\n\nWhen you are hypothyroid, higher quantities of TSH are circulating in your blood as your body attempts to foster increased production of thyroid hormones.  The reverse is true with hyperthyroidism, in which TSH levels are below normal and circulating thyroid-hormone levels are high.\n\nTo determine the cause of hyperthyroidism, doctors often use radioactive iodide uptake tests, which track the amount of iodide absorbed by the thyroid gland. Iodide, obtained from the foods we eat, is a key ingredient in the manufacture of thyroid hormone, so the amount of iodide the thyroid absorbs is a reliable indicator of how much hormone the gland is producing.  For this test, you must swallow a small amount of radioactive iodide in liquid or capsule form.  After a predetermined wait, the doctor places an instrument over your neck to measure how much of the radioactive iodide has gathered in your thyroid.\n\nIf the results of this test suggest that the gland is collecting excessive amounts of iodide, the doctor may then conduct a radioactive iodide uptake scan.  In this test, the doctor uses a special film to create a picture that shows the exact location of the radioactive iodide in your thyroid gland.  The scan will reveal, for example, if the iodide is collecting in adenomas, indicating that the nodules are responsible for the excess hormone.  If the scan shows that the iodide is spread equally throughout the tissue, the whole thyroid is involved in the excess production.\n\nSome doctors believe that blood tests may not be sensitive enough to detect milder forms of hypothyroidism.  Instead, they advocate monitoring your body's basal (resting) temperature.  To track your basal temperature accurately, you must closely follow certain guidelines:  Shake the thermometer below 95° F at night and place it where you can reach it without getting out of bed.  The following morning, before you get out of bed, take your temperature via your armpit for 10 minutes while staying as still as possible.  Keep records of your temperature for at least three days.  (Women should do this during the first two weeks of the menstrual cycle, as their basal temperature may rise during the latter half.)  Normal basal body temperatures fall between 97.4° F and 97.8° F.  If your basal temperature is consistently low, you could be mildly hypothyroid.\n\nIf you have one or more adenomas, your doctor will want to keep careful records of when they were first found and how they develop, since not all adenomas produce excess thyroid hormone. In fact, most of these nodules are not malignant, especially if they remain the same size over long intervals.  (Cancerous tissue, by contrast, will undergo noticeable growth.)  Nodules that appear suddenly are typically fluid-filled cysts and are often benign.  They can be evaluated with a noninvasive ultrasound exam.  If blood tests indicate that the nodules are producing excess thyroid hormone, and if you have other symptoms, your doctor will treat you for hyperthyroidism.\n\nIn any case, you should receive periodic checkups if you have a nodule on your thyroid gland, since you may become hyperthyroid in the future.  If your blood tests show elevated hormone levels, your doctor may recommend other tests, including radioactive iodide uptake tests and scans that indicate whether the nodules are "hot" or "cold."  Hot nodules, or those that are actively trapping iodide and producing too much thyroid hormone, are rarely cancerous.  But cold nodules -

Name: iodine \nSymbol: I \nAtomic number: 53 \nAtomic weight: 126.90447 (3) \nCAS Registry ID: 7553-56-2 \n Group number: 17 \nGroup name: Halogen \nPeriod number: 5 \nBlock: p-block \n \nHere is a brief description of iodine.\n\nStandard state: solid at 298 K \nColour: violet-dark grey, lustrous \nClassification: Non-metallic \nIodine is a bluish-black, lustrous solid. It volatilises at ambient temperatures into a pretty blue-violet gas with an irritating odour.\n\nIt forms compounds with most elements, but is less reactive than the other halogens, which displace it from iodides. Iodine exhibits some metallic-like properties. It dissolves readily in chloroform, carbon tetrachloride, or carbon disulphide to form beautiful purple solutions. It is only slightly soluble in water. Iodine compounds are important in organic chemistry and very useful in medicine and photography. Lack of iodine is the cause of goitre (Derbyshire neck). The deep blue colour with starch solution is characteristic of the free element. It is assimilated by seaweeds from which it may be recovered, and is found in Chilean saltpetre, caliche, old salt brines, and salt wells.\n\nYou can never know too much :)

Heat the crystals. If it  has water of crystallisation then it will eventually leave the substance. Collect any vapours using a liebig condenser then determine if that is water. Problem is, if you heat it, will it decompose?

They can contain unsafe high levels of iodine.\n\nAnd aren't they bloody expensive???

Iodine does not block the formation of T3 and T4, but the key element. During the process of transformation, iodine binds with other polymers and become ionized, a state called iodide. Only when ionized, can iodine be active and interact with other elements. \n\nThe cause of goiter is iodine deficiency, and the body tries to compensate the deficiency with enlarged thryroid gland. T3 and T4 both are beneficial to goiter. The difference is T4 is usually converted to T3 by deiodinases, so T3 is considered as the major thryroid hormone, altough the plasma concentration of T4 is much higher.

You could dissolve the crystal compound in water and measure the temperature change and specify whether there is an endothermic or exothermic change.  \n\nYou will need a thermometer.  Be careful as some crystal compounds are violently exothermic when dissolved in water.\n\nAndy

I've used it as a process in which a compound is dissolved in their recrystalization solvent (found in the Merck index) then filtered. The new filtered solution is allowed to cool and the compounds recrystallize creating more pure crystals. \nLook up types of organic purifications.
