On-Site Diagnostic Testing at Urgent Care: Labs and X-Rays Without the Wait

When you're not feeling well or have an injury that needs more than a visual exam, quick and accurate testing is essential. Many urgent care clinics offer on-site diagnostic testing, including laboratory services and digital X-rays, to provide fast answers and appropriate treatment—all in one visit.
Common lab tests performed on-site include rapid strep and flu tests, urinalysis, and urine pregnancy testing. These rapid diagnostics help providers confirm infections, and make timely treatment decisions.
San Antonio Regional Hospital’s urgent care clinics are also equipped with digital X-ray technology, allowing providers to evaluate possible bone fractures, sprains, lung infections, and other internal concerns. Whether it’s a lingering cough, a sports injury, or abdominal pain, having these services in-house means fewer delays and no need to travel elsewhere for imaging. *(Some insurance plans do not cover in-house X-ray.)
