Empowering you and your patients with the support you need, when you need it

Hormones are true biomarkers of health, and evidence continues to indicate the interrelationships between chronic cardiometabolic diseases. Create a personalized approach to reduce risk by testing your patients early to get them on a faster path to diagnosis, treatment, and management of their condition. If we can improve the gap in diagnosis rate for thyroid conditions, PCOS, and hypogonadism, we can uncover those at risk to identify and prevent cardiometabolic comorbidities. With 50 years of expertise in endocrine care, Quest makes it easy with 600+ medical experts on call, 225+ tests, and step-by-step guideline-based testing algorithms.

Quest is dedicated to supporting you with testing algorithms for common endocrine disorders

Thyroid conditions 

- 20 million Americans are affected by a thyroid disorder, and up to 60% are unaware of their condition1

- Women are 5 to 8 times more likely to have a thyroid disorder, with 1 in 8 women estimated to develop a thyroid disorder during her life1

- Thyroid disorder symptoms vary according to the type of dysfunction and may initially be attributed to other causes


Choose the right test at the right time.

Polycystic ovary syndrome (PCOS)

- 5-18% of women are affected by PCOS, with health impacts across their lifespan2-4

- 75% of individuals with PCOS remain undiagnosed due to variability in presentation and differences in published clinical diagnostic criteria5

- Approximately half of patients with PCOS will develop type 2 diabetes by age 405


Testing early means identifying risk factors faster.

Autoimmune diseases


-It is estimated that ~35% of men over age 45 have hypogonadism6

- 30%-50% of men with obesity or type 2 diabetes have hypogonadism7

- Fewer than 5% of affected patients receive treatment for hypogonadism8
