Express Health Urgent Care offers flu testing at our various locations in New York City. We are open for extended hours, including evenings, and we offer walk-in services, so you can receive testing when you need it, without the need for an appointment. We are equipped to diagnose and treat a variety of illnesses, injuries, and medical conditions such as flu and other respiratory infections.   It is recommended to get a flu test if you are experiencing symptoms of the flu. If you are at high risk for complications from the flu, such as young children, older adults, pregnant women, and people with certain chronic health conditions, it may be a good idea to get tested even if your symptoms are mild. It is also recommended to get a flu test if you have been in close contact with someone who has the flu, or if you work in a setting such as a school or a hospital where the flu is prevalent.
