The Endocrine system comprises of the endocrine glands such as the pituitary, thyroid, pancreas, adrenal, etc. These glands secrete hormones that regulate the body's metabolism, growth, sexual development and function. Endocrine tests help in assessing the normal functioning of the endocrine gland by checking the hormone levels. The tests detect the imbalance in hormonal levels. The various tests, their advantages and uses are described in the report. The Endocrine testing market is driven by the increasing incidences of endocrine disorders such as diabetes, thyroid disorders, infertility, etc. This has also resulted in the development of new technologies, which is driving the growth of this market. High development costs required for developing new technologies could impede growth of this market. The opportunities for this market are tremendous as rising incidences of endocrine disorders and increasing health care awareness would require rapid, sensitive and low priced tests.
