The National Urban League and retailer Walgreens are hosting their fourth annual Wellness Tour, which features free blood pressure, bone density, glucose, cholesterol, body mass index and waist circumference testing.

The health screenings are offered in efforts to promote early detection and raise awareness about preventable diseases in low-income communities.

“National Urban League is pleased once again to join Walgreens in empowering urban communities through our fourth annual Wellness Tour,” said Marc H. Morial, president and CEO of the National Urban League, in a press release. “Health screenings are essential to disease detection and prevention, especially in diverse communities plagued by lack of access to affordable health care. Our local programs and partnership with Walgreens through the Wellness Tour is part of an ongoing effort to help close the equality gaps that still exist concerning the health and wellness of the African-American community.”

Screenings are open to District residents 18 and older.
