Glucose Tolerance Test Market Revenue and Trends 2025 to 2033

The global glucose tolerance test market revenue was valued at USD 56.76 billion in 2025 and is expected to attain around USD 122.47 billion by 2033, growing at a CAGR of 10.09% during forecast period. This market growth is driven by the global surge in the number of cases of diabetes and prediabetes, coupled with growing demand for early, accurate diagnostic solutions.

What are the Major Factors Driving the Growth of the Glucose Tolerance Test Market?

The glucose tolerance test market continues to grow rapidly, driven by the rising incidence of diabetes and prediabetes around the world. With lifestyle-related health concerns, such as sedentary lifestyles, obesity, and unhealthy eating habits, are driving the demand for early diagnostic tools like GTT. In addition, increased awareness of preventive healthcare and government initiatives aimed at reducing the burden of metabolic disorders are also driving the market growth. New diagnostic tests based on advanced technology, like non-invasive tests and faster results, are increasing adoption rates.

Beyond the health issues related to lifestyles, the growing aging population, which is more prone to glucose intolerance, is expected to fuel market growth. In addition, ongoing advances in diagnostic technology and rising healthcare spending open up new growth avenues for the market.

Segment Outlook

• By product type, the oral glucose tolerance test (OGTT) kits segment held the largest share of the market in 2024. This is due to the fact that these kits offer an accurate and comprehensive analysis of blood glucose levels. Their widespread use in clinical settings further supports segmental growth.
• By mode of testing, the laboratory-based testing segment led the market in 2024, as it offers high analytical precision across a standardized approach to diabetic testing and is globally recognized as a reliable diagnostic test.
• By application, the gestational diabetes screening segment dominated the market in 2024 because of a significant rise in the number of cases of gestational diabetes. Increased awareness of early diagnosis of diabetes further bolstered segmental growth.
• By end-user, the hospitals segment dominated the market in 2024 because of the increased patient volumes, driven by the availability of advanced diagnostic solutions and qualified professionals, which builds trust among patients.

Regional Insights

North America registered dominance in the glucose tolerance test market in 2024. This is mainly due to its robust healthcare infrastructure, high levels of awareness about diabetes screening, and the availability of advanced diagnostic services. Increased healthcare spending and an aging population further bolstered regional market growth.

Meanwhile, Asia Pacific is expected to grow at the fastest rate in the upcoming years due to the rising number of diabetes cases, better access to healthcare services, and increasing urbanization in countries such as India and China. Growing awareness of gestational and type 2 diabetes further propels the demand for glucose tolerance tests in the region.
