Firstly, in order to diagnose whether your pipeline loot levels are within normal limits and whether your bole is producing the right amounts of endocrine glands needed to effectively utilize and store the sugars that we consume, there are a number of diagnostic tests.

Another confirmatory test for diabetes is the glucose tolerance test, whereby you will be made to give two blood samples. To bring up for the test you have to eat a normal balanced diet for upto three days preceding the tests. Then, like for the fasting blood sugar test, you have to fast overnight, for duration of about 8 hours and the first blood sample is collected.

The morning when the test is performed, you will be first injected with insulin, which is a substance which will lower your blood sugar. Our bodys normal response to low blood sugar levels is to secrete two hormones growth hormone (GH) and adrenocorticotropic hormone (ACTH), which in turn stimulates the secretion of another hormone called cortisol (National Institutes of Health (NIH), 2011). After the insulin injections timed blood samples will be taken and the levels of GH and cortisol will be canvas and compared against the normal reference range s to see whether the normal secretion of these substances in your body is present or not (National Institutes of Health (NIH), 2011). In order to evaluate the functioning of the thyroid gland gland, which is an important gland located in our neck, there are several tests. A complete panel of tests to assess proper functioning of the thyroid gland is termed as the thyroid function test. This panel includes levels of different form of thyroid hormones such as T3 and T4 which are different circulating forms of thyroid hormone in our bloodstream (American Thyroid Association, 2005).
