- Iodoform Reaction. The iodoform test indicates the presence of an aldehyde or ketone in which one of the groups directly attached to the carbonyl carbon is a methyl group. Such a ketone is called a methyl ketone. In the iodoform test, the unknown is allowed to react with a mixture of iodine and base.Hydrogens alpha to a carbonyl group are acidic and will react with base to form the anion, which then reacts with iodine to form an alpha-iodo ketone.uch a ketone is called a methyl ketone.

Thyroid Function Tests Thyroid function tests are blood tests which help to check the function of the thyroid gland. They are mainly used to detect hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid). Note: the information below is a general guide only.

Thyroid Gland Function Tests Iodine Uptake Scan. A means of measuring thyroid function is to measure how much iodine is taken up by the thyroid gland (RAI uptake). Remember, cells of the thyroid normally absorb iodine from our blood stream (obtained from foods we eat) and use it to make thyroid hormone (described on our thyroid function page).herefore, all scans are now done with radioactive iodine. Both of the scans above show normal sized thyroid glands, but the one on the left has a  HOT  nodule in the lower aspect of the right lobe, while the scan on the right has a  COLD  nodule in the lower aspect of the left lobe (outlined in red and yellow).

Glucose tolerance test A glucose tolerance test, also called an oral glucose tolerance test (OGTT), checks how your body regulates your sugar levels. Sugar, or glucose, is found in many of the foods you eat. The test is used to diagnose diabetes in pregnancy (gestational diabetes) and is offered to all pregnant women (NCCWCH 2008).

- Highlights. 1  A urine glucose test measures the level of glucose, or sugar, in your urine. 2  If your urine glucose test results are abnormal, your doctor will perform additional tests to determine the cause.  High glucose levels often indicate diabetes, a group of diseases that affects the way the body handles glucose.

What Is a Radioactive Iodine Uptake Test? The thyroid gland absorbs iodine from the body to produce T4. As part of the RAIU, you will be given a pill or liquid containing radioactive iodine. The scan will show how much of this radioactive iodine is absorbed by the thyroid. This is a measure of how well the thyroid is functioning.

Diabetes, Type 2  In-Depth Report Test Overview. The oral glucose tolerance test (OGTT) measures the body's ability to use a type of sugar, called glucose, that is the body's main source of energy. An OGTT can be used to diagnose prediabetes and diabetes. An OGTT is most commonly done to check for diabetes that occurs with pregnancy (gestational diabetes).

What do you mean by iodoform test? The iodoform test or iodoform reaction is a qualitative chemical test for the detection of ketones and aldehydes carrying an alpha methyl group. The reagents are iodine and sodium hydroxide.Only methyl ketones, or alcohols with the feature: CH3CH(OH)-R may undergo this reaction.thanal is the only aldehyde to give the iodoform reaction. Finally, OH- (aqueous) is added, which reacts with, for example, the triiodoacetone. CH3COCI3 + OH- → CHI3 + CH3COO-Iodoform, or triiodomethane (I3CH) is a pale yellow substance. It is therefore a solid at room temperature.

Thyroid Scan For thyroid tests, radioactive iodine typically is used. Your thyroid and most types of thyroid cancer absorb iodine naturally. After the radioactive iodine accumulates in the thyroid tissue, the radioactive emissions can be detected by equipment outside the body, allowing your doctor to evaluate your thyroid function. A radioactive iodine uptake test (RAIU) test measures thyroid function without imaging. 2  A whole-body thyroid scan, or metastatic survey, is used to evaluate patients with thyroid cancer. 3  The scan evaluates the spread of thyroid cancer to other parts of your body.

Electrodiagnostic Testing Electrodiagnostic Testing. Electrodiagnostic tests measure the electrical activity of muscles and nerves. By measuring the electrical activity they are able to determine if there is nerve damage, the cause of the damage, and if the damaged nerves are responding to treatment. An electromyogram (EMG) is a test that measures the electrical activity of a muscle.

Being Deficient in Iodine Affects Thyroid Function A 24-hour urine iodine collection is the most common medical test for diagnosing iodine deficiency. The body eliminates 90% of the iodine ingested daily in the urine, therefore, the level of iodine in urine is a good indication of the amount of iodine found in the body. Iodine deficiency causes a number of medical disorders including goiter and cretinism.
