"This performance is due to growth of new physician and hospital customers, more favorable test mix that includes greater adoption of advanced diagnostics," Quest CEO Jim Davis said.

Here’s what experts say your AMH level can and can’t tell you about your fertility. “An AMH test could be the first step.

If it feels like you’ve been hearing more about testosterone lately, you’re not wrong. However, the question of whether or not you should get your own testosterone checked isn’t so straightforward. To put it simply, if you’re not experiencing persistent symptoms associated with low testosterone, you have no reason to get your levels checked—regardless of what they might be. “If you're otherwise feeling well, I really don't advocate just going on a fishing expedition,” says Sanjay B. Dixit, MD, medical director of cardiometabolic endocrine and wellness clinical solutions at Quest Diagnostics. “That's actually one of the key points in the Endocrine Society’s guidelines from 2018, that they do not recommend testing in otherwise asymptomatic men.”

Despite the national hepatitis C elimination goals for 2030 to achieve at least 80% of persons with hepatitis C to achieve viral clearance, the goals across states is consistently falling under. In fact, analysis of data collected during 2013–2022 from a national laboratory found that HCV clearance or cure proportions among persons with virus by state was between 10% to 51%.1This data was published in the Centers for Disease Control’ and Prevention's (CDC) MMWR late last week. The investigators collected 10 years of data from January 1, 2013 through December 31, 2022 utilizing information from the national laboratory company, Quest Diagnostics. They analyzed patients from all 50 states and the District of Columbia.

A blood test could help reduce costs for health plans by reliably identifying patients who might be able to safely forgo chemotherapy after surgery for stage II colorectal cancer, according to a study published in JAMA Health Forum, a member of the JAMA Network. Researchers from Haystack Oncology, a Quest Diagnostics company and developer of the Haystack MRD tumor-informed ctDNA MRD technology, City of Hope and the Walter and Eliza Hall Institute of Medical Research conducted the study. In June 2022, a randomized clinical trial (DYNAMIC) demonstrated that a tumor-informed ctDNA MRD test performed on patients with stage II colorectal cancer reduced the application of adjuvant chemotherapy (ACT) by nearly half (15% vs. 28%) without compromising recurrence-free survival.

Workers are cheating on drug tests at the highest rate in more than 30 years, according to one of the U.S.’s largest drug-testing labs. The increase in tampered tests came from samples collected in 2023. About 31,000 drug screens out of 5.5 million showed signs of cheating, according to Quest Diagnostics. “Some American workers are going to great lengths to attempt to subvert the drug-testing process,” said Dr. Suhash Harwani, senior director of science for workforce health solutions at Quest. The percentage of urine samples that came back positive for drugs among the U.S. workforce remained steady at a two-decade high for the third year in a row. But the substantial rise of tampering, as well as the patchwork of new marijuana laws across the U.S., have intensified challenges for employers seeking to keep drugs out of the workplace.
