Vitamin B12 Testing near me in Deerfield, Illinois

My sister got covid unfortunately while we were traveling to Chicago. We called the closest urgent care at about 12:40 pm, which happened to be Aayu in Wicker Park. They said they could see her before 1 pm. She wasn't in the clinic long to get a test to confirm if she had it, and they expedited the test and emailed her by 3 pm to say she had it. Then they expedited a paxlovid prescription right up the street that she was able to pick up quickly. By 5 pm she was quarantined completely, and she was better already a few days later. Thank you SO MUCH, Aayu, for taking such good care of my sister. I know her long-term health and immediate outcome are both better for having been there. I appreciate you and your efficiency of care so much! I will recommend you to anybody and everybody in that area.
