The thyroid function test market is expected to witness a CAGR of 6% during the forecast period. Certain factors that are driving the growth of the market include rising incidence of thyroid disorders, increasing consumption of tobacco and alcohol, and sedentary lifestyle.
Thyroid diseases have become a significant public health concern across the world. The risk factors include genetic background, environmental exposures, insufficient iodine intake, exposure to polychlorinated biphenyls, radiation from nuclear fallout and medical radiation, and alcohol and tobacco consumption, among others. As per the American Thyroid Association, approximately 20 million citizens in the United States have some form of thyroid disease (2017). The thyroid function test market is witnessing substantial growth due to the high prevalence of thyroid disorder, as well as due to the rising consumption of alcohol and tobacco.
Alcohol consumption is considered to be one of the most significant risk factors for disease and disability. Globally, high-income countries of the developed regions have the highest alcohol consumption, with 50.1% of the United States population (adults over 18 years of age) being regular drinkers. As per various studies, there is a negative relationship between the hypothalamic-pituitary-thyroid (HPT) axis and alcoholism. Regular drinking inhibits the peripheral thyroid hormones, frees T3 and T4, and reduces the activity of type II 5’-deiodinase, which further affects the metabolic function, leading to the development of hypothyroidism. Tobacco also induces changes in thyroid function tests, such as the decrease in TSH and increase in thyroid hormones.
However, the shortage in endocrinologists is expected to limit the growth of the thyroid function test market. Endocrinologists play a pivotal role in treating patients with some of the most complex and prevalent conditions faced in the United States today. At present, fewer than 6,500 endocrinologists are available in the country to provide care for the millions of patients who have diabetes, thyroid disease, osteoporosis, and other hormonal conditions. Another factor contributing to the slow growth of the thyroid function test market is the difficulty associated with the interpretation of thyroid blood tests.
Key Market Trends
TSH Test is Expected to Hold the Largest Market Share in the Test Type
TSH measurement has recently gained a dominant role in thyroid function testing, further facilitating cost-effective disease screening, and also introducing new definitions of subclinical hypothyroidism or hyperthyroidism, along with delivering biochemical treatment targets. TSH (thyroid stimulating hormone) test measures how much of this hormone is in a patient’s blood. The test finds out whether the thyroid gland is working the way it should. There is very little to no risk in taking the blood test. The slight pain or bruising at the spot where the needle was put in goes away quickly.
However, TSH test cannot explain why TSH levels are too low or too high. If the test results are abnormal, the healthcare provider generally orders additional tests to determine the cause of the thyroid problem. These tests may include T4 thyroid hormone tests, T3 thyroid hormone tests, tests to diagnose Graves' disease (an autoimmune disease that causes hyperthyroidism), or tests to diagnose Hashimoto's thyroiditis (an autoimmune disease that causes hypothyroidism).
North America Dominates the Market and Expected Keep its Position in the Forecast Period
Based on the geographical analysis, North America is predicted to lead the thyroid function test market, owing to the prevalence of thyroid cancer in the United States. As per the National Cancer Institute, in 2017, there were around 218,853 people living with thyroid cancer in the United States and the number of new cases of thyroid cancer was 14.5 per 100,000 men and women per year.
The North American region is also likely to witness a major growth, owing to several initiatives such as the compulsory screening of newborns for congenital hypothyroidism, revolutionary research work on thyroid hormone function, cost-effective methods to detect thyroid cancer, promising research on Graves’ disease, etc., which may further lead to improved prognosis and new preventive treatments of thyroid diseases.
The thyroid function test market, which is highly competitive, consists of a number of major players. Companies, such as Abbott, Autobio Diagnostics, BioMérieux SA, Danaher Corporation, DiaSorin SpA, F. Hoffmann-La Roche Ltd, Qualigen Inc., Qualigen Inc., Siemens Healthineers, and Thermo Fisher Scientific Inc., among others, hold a substantial market share in the thyroid function test market.
Recently, various developments have been taking place in the market. For instance, in May 2018, Interpace Diagnostics Group reported that the company entered into an agreement with the Vanderbilt University Medical Center (VUMC), which would enable all physicians across the Vanderbilt system to gain access to both ThyGenX(R) (now ThyGeNEXT(R)) and ThyraMIR(R) for patients with indeterminate thyroid nodules.
