AI, new diagnostics, and shifting care delivery models are among the clinical laboratory predictions for 2026. Cardiometabolic testing is one example, where labs are being asked to look beyond single endpoints. “In 2025, we saw many individuals focus on weight loss as a means of potentially improving their cardiometabolic health,” says Mouris Saghir, PhD, vice president and general manager for cardiometabolic, endocrine, and wellness at Quest Diagnostics.

Lab testing companies including giants Quest Diagnostics and LabCorp are pressing Congress to stop hundreds of millions of dollars of Medicare cuts for diagnostic tests that are due to take effect at the end of January. Their push could add to the health care issues piling up on lawmakers' plates as the calendar flips over. Clinical lab companies say letting the cuts take effect will leave them with less money to spend on creating new diagnostics or technologies to generate quicker results. "Labs play a critical part in trying to keep the nation well — identifying that risk before it ever even happens," said Yuri Fesko, chief medical officer at Quest.

Quest Diagnostics, a cancer treatment laboratory located in Lewisville, was honored by the Lewisville City Council after developing a medical breakthrough that could decrease the risk of diseases returning to treated patients. The laboratory was recognized for its achievement in developing Haystack MRD, a non-invasive, tumor-informed MRD test that searches for tiny tumor fragments in people who have previously or currently have a solid tumor.

In our latest podcast, Elizabeth Marlowe, PhD, D(ABMM), discusses the findings of Quest Diagnostics' large US HIV testing study, which showed a significant decline in HIV drug resistance across major antiretroviral classes, reflecting the impact of modern high-barrier therapies and improved viral suppression.

Even though exercise is good for us, working out can sometimes feel stressful: fitting in time for the gym, making sure we have clean workout clothes, monitoring our daily step count, pushing our runs, rides, and reps to be faster, harder, and just, well, more. If this sounds familiar, you’ll be pleased (and surprised!) to know that the latest fitness trend is all about doing less. If this sounds familiar, you’ll be pleased (and surprised!) to know that the latest fitness trend is all about doing less. In fact, it’s not a traditional workout at all—but it does have some legit benefits for physical health and mental wellbeing. “Getting up and moving around is good for your mental health,” says Marc Penn, M.D., Ph.D., FACC, a senior advisor and medical director of cardio-metabolic endocrine at Quest Diagnostics. Low-intensity activity can improve mood. Plus, clutter can add to stress and mental health issues, so if you’re using your Zone Zero time to tidy up, you get a two-for-one.
