Diabetes & prediabetes

First, know the risk with earlier diagnostic insight

As obesity rates continue to rise and the US contends with a growing aging population, the need for diabetes risk identification, prevention, and management is more critical than ever.1

Quest Diagnostics offers a comprehensive array of laboratory testing for diabetes to help you manage the disease in all of your patients, no matter where they are on the care continuum, ensuring continuity of care.

Identify insulin resistance, metabolic syndrome, prediabetes, and diabetes risk early—and in more patients—to help prevent or slow progression of the disease.

Learn more about diabetes and prediabetes risk

Start the right treatment plan with a differential diagnosis that goes beyond diabetes type 1 and type 2, including latent autoimmune diabetes in adults (LADA) and monogenic diabetes (MODY).

Learn more about making a differential diagnosis

Rely on our testing based on guidelines issued by the American Diabetes Association (ADA) to effectively monitor and manage diabetes patients and help them delay or avoid the potential for complications.

Defining the intersection of chronic conditions: a prevention-focused approach to cardiometabolic disease

With more people at risk for cardiovascular disease than ever before, the Quest Cardiometabolic Center of Excellence™ at Cleveland HeartLab® is advancing a prevention-focused approach for heart disease and associated metabolic conditions.

Cardiovascular disease (CVD) is strongly associated with type 2 diabetes (T2DM), chronic kidney disease (CKD), and nonalcoholic fatty liver disease (NAFLD). Through significant investments in novel technology, the Cleveland HeartLab® is fostering innovation to detect these conditions in their early stages, providing the opportunity for stage-targeted intervention and improved clinical outcomes.

  • Cardiovascular disease is the leading cause of death for individuals who have T2DM,stage 4-5 CKD,3 and NAFLD.4
  • Those who have T2DM have a 2 to 3 times higher risk of fatal coronary heart disease.5
  • Nearly 40% of persons who have diabetes and more than 30% of those who have hypertension also have CKD.6 The leading causes of end-stage renal disease are diabetes and hypertension.7
  • More than 75% of those who have T2DM have NAFLD.8
