Alzheimer's disease is the most common form of dementia and affecting about 6 million people in the United States. A simple blood test is providing a new way for doctors to detect the potential risk of Alzheimer's disease in its early stages. Here to talk about this groundbreaking new approach is a board-certified neurologist and medical director of neurology at Quest Diagnostics.

Diagnostics firm Diadem said Wednesday that it has licensed exclusive US rights to its AlzoSure Predict Alzheimer's blood test to Quest Diagnostics. Under the agreement, Quest can develop, validate, and market the assay, which is intended to identify individuals likely to progress to Alzheimer's disease, as a laboratory-developed test in the US. AlzoSure Predict measures a variant of the p53 protein that has been linked to Alzheimer's disease.

Laboratory operator Quest Diagnostics on Tuesday raised its full-year sales forecast after beating third-quarter expectations for revenue and profit, buoyed by a recovery in routine testing. The company raised its full-year net sales forecast to $9.19 billion to $9.24 billion, from its previous expectations of $9.12 billion to $9.22 billion. Sales from Quest's base business, which includes a range of diagnostic tests for allergies, chronic diseases and cancer, rose 4.6% to $2.27 billion in the third quarter. That extends a rebound in routine health check-ups delayed due to pandemic-related lockdowns for diagnostic firms like Quest and eases the blow from plunging demand for COVID-19 tests.

Dialysis company Neway said Thursday that it has entered a strategic lab services arrangement with Quest Diagnostics to speed dialysis lab testing and reduce testing costs for patients with end-stage renal disease (ESRD). Under the terms of the agreement, Neway will use Quest's lab network to provide local testing services, enabling next-day results while also reducing sample transportation costs.

Self-service has seen incredible growth in recent years, and this is just the beginning. 81% of customers want more self-service options. Here are 20 of the best examples of self-service:

13. Quest Diagnostics Cuts Wait Time with Kiosks
Medical lab company Quest Diagnostics cuts wait times with interactive kiosks that patients can use to check in, upload insurance information, and make payments. The devices help patients be seen faster, allowing medical staff to spend more time working with patients and less on administrative tasks.

Stamford-based Americares is partnering with Quest Diagnostics to provide 10 clinics across the U.S. with no-cost diagnostic services for one year as a means of increasing access to care for low-income, uninsured and underinsured patients.

Rutgers and Quest Diagnostics are expanding their collaboration to further improve access to critical primary care services for uninsured patients of the university’s Health Outreach Practice Experience (H.O.P.E.) Clinic in Plainfield. Resources from the Quest Diagnostics Foundation will enable the clinic to double its capacity by providing primary care services for a second day of the week.

Quest Diagnostics has secured breakthrough device designation for its adeno-associated virus (AAV) test, AAVrh74 ELISA assay, from the US Food and Drug Administration (FDA). The test is an enzyme-linked immunosorbent in vitro diagnostic assay intended for the semi-quantitative detection of antibodies (IgG) to AAVrh74 capsid in the serum of humans. Quest also expanded collaboration with Sarepta to develop complementary diagnostics for Sarepta's gene therapies.

Researchers from Quest Diagnostics and collaborators have found that changes in levels of the cardiovascular risk marker free myeloperoxidase (MPO) appear correlated with an individual's overall mortality risk. The finding, described in a study published last month in PLOS One, indicate that longitudinal measurement of MPO could help physicians assess patients' mortality risk and response to interventions.

Quest Diagnostics has partnered with Envision Sciences to commercially launch a novel prostate cancer biomarker test to help in identifying patients with more aggressive forms of the disease, Quest Diagnostics and the University of South Australia announced in separate news releases.1,2"Our goal for this innovative prostate biomarker test is to improve the accuracy of grading prostate cancer biopsies.
