Walmart stores will be hosting free health screenings across the U.S. Saturday. 

The event is part of Walmart Wellness Day and will include free blood glucose screenings, blood pressure screenings, body mass index screenings, low-cost immunizations administered by health professionals, and in some locations customers can also take advantage of free vision screenings. 

The free screenings will be offered between 10 a.m. and 2 p.m. 

This will be the second Walmart Wellness Day for which the company has teamed up with the American Diabetes Association (ADA) beyond event day, offering additional support to customers whose screening results indicate a risk of developing type 2 diabetes.

The American Diabetes Association estimates nearly 8 million people with diabetes are undiagnosed.

Each Walmart customer who learns of potential risk will be offered the opportunity to receive follow up information from the ADA.

Tens of thousands of customers took advantage of this free service following the previous Walmart Wellness day event in June.
