We recently published a list of the 12 Best Diagnostics Stocks to Invest In Right Now. In this article, we are going to take a look at where ICON Public Limited Company (NASDAQ:ICLR) stands against the other best diagnostics stocks to invest in right now.
Overview of the Clinical Diagnostics Market
According to a report by Mordor Intelligence, the clinical diagnostics market has a size of $88.79 billion as of 2025. It is expected to grow at a compound annual growth rate (CAGR) of 5.48% between 2025 and 2030, reaching $115.94 billion at the end of the forecast period. While North America is the largest market in the domain at present, Asia-Pacific takes the lead as the fastest growing.
As per Grand View Research, the growth in the global clinical diagnostics industry is attributed to the rising demand for lab automation and the development of specialized tests for disease management and early disease detection. In addition, the growing use of point-of-care diagnostics products has also driven a decentralization trend in the healthcare industry.

AI in Diagnostics Healthcare: Is A New Trend Emerging?
One of the primary trends emerging in the sector is the growing use of artificial intelligence. AI-powered diagnostic tools are revolutionizing the interpretation of medical images with high accuracy, leading to increased adoption. These tools not only improve disease diagnostics but also allow medical professionals to develop more effective and personalized treatment plans, elevating the overall healthcare experience.
On February 24, GlobeNewswire reported that the US AI diagnostics market was worth around $655 million in 2024, as per estimates by Precedence Statistics. It is expected to grow at a CAGR of 20.7% between 2025 and 2034, reaching $4.29 billion by the end of the forecast period.
On February 4, Eric Lefkofsky, founder and CEO of Tempus AI, appeared on CNBC to talk about the impact of generative AI in diagnostics healthcare, among other things. He was of the view that generative AI and large language models aren’t more impactful in any other avenue as much as they are in healthcare. Diagnostics sit at the center of healthcare, as almost every other major decision a doctor makes is undertaken after ordering some kind of laboratory test. If we can make diagnostics more intelligent, it would be possible to route patients to the best possible and most optimal therapy.
Generative AI is thus allowing access to new tools that help structure and make sense of disparate information and use that information, whether it be physician progress notes, pathology reports, molecular data, CAT scans, MRIs, or others, to make sure that the patients are on the optimal therapy path. He further said that the promise of this technology is twofold: it is enormous in helping patients live better and longer lives while reducing the substantial waste in the US healthcare system. Generative AI is thus significantly impactful in healthcare diagnostics.
