Needing lab tests can be stressful. Waiting on them can be worse. Urgent Care 24/7 offers walk-in lab testing for most any test you might need, including blood, urine, and even STD tests. Some rapid testing results are immediate, most other diagnosis are back in one to three days. Lab testing at Urgent Care 24/7 is more affordable than going to the lab itself. Labs may be ordered by a provider or you may walk-in and request lab work without seeing a provider. A pre-test or post-test provider visit is required for prescription or diagnosis.
