Walmart and Quest Diagnostics are partnering to offer consumer-initiated laboratory testing. Consumers will be able to purchase more than 50 high-quality lab tests ordered by health care providers, including those for general health, digestive health, allergy, heart health, women’s health and infectious disease. Depending on the test, some users will be prompted to schedule an appointment at one of Quest’s 2,220 patient service centers across the United States, including at select Walmart stores.
