Thyroid function tests (TFTs) are the main diagnostic criteria for a thyroid disease.
These are however done in the face of other clinical findings and patients symptoms (differs for hypo and hyperthyroidism)
Diffuse thyroid parenchymal disease just means disease of the thyroid throughout the body of an organ. It is not a diagnosis, but only an observation based on thyroid ultrasound.
These symptoms are too vague to guess a diagnosis, however a common diagnosis with this set of symptoms is goiter resulting from autoimmune thyroid disease which can be present with normal thyroid labs.
Graves' Disease is an autoimmune condition in which the body makes antibodies that stimulate the excess production of thyroid hormones - called hyperthyroidism. For appropriate diagnosis and treatment of thyroid dysfunction, please seek the help of a board certified endocrinologist who specializes in thyroid problems.
Tc99m and I131 arent used in thyroid uptake and scan. Specically I123 is used to evaluate thyroid uptake and is also used to perform a scan mostly in addition to a pinhole collimator. Tc99m can be used just for the purpose of size and shape of thyroid but ultrasound is more specific for that and does not introduce a dose of radiation to the patient.
For some reason a person with higher than normal thyroid hormone levels may have an autoimmune disease called Grave's Disease, an inflammation of the thyroid gland, or has over used thyroid medication.

Diagnosis (Dx) is used to determine the cause of a disease or condition. There are a number of steps. The use of various tests are used to see if the doctor has guessed correctly or has to begin again.

Some alternate names for thyroid disease are: Grave's Disease, Hashimoto's thyroiditis, autoimmune thyroiditis, thyroid struma, hypothyroidism, hyperthyroidism and thyroid carcinoma...just to name a few.
Seeing as the thyroid (thyroid gland) is not a disease but one of the endocrine glands located in our body (specifically in the neck area below the thyroid cartilage). Then no, you cannot "contact" a thyroid from anyone. Since normally, we are all supposed to have a thyroid gland. Well if you meant to say Typhoid fever, then yes, it is indeed a communicable disease.
Thyroid disease affects the thyroid gland. This gland is in the neck, in the shape of a butterfly with lobes on each side. The thyroid gland excretes hormones.
