On-Site Diagnostic Imaging and Lab Services

Walk-in diagnostic services mean you skip the back-and-forth between your doctor’s office and a separate lab or imaging center. PACS Urgent Care offers comprehensive walk-in diagnostic services — X-ray, EKG, lab testing, and rapid in-office tests — 7 days a week.

Why Choose Walk-In Diagnostic Services at PACS

According to the FDA’s information on in-office diagnostic tests, modern point-of-care testing delivers fast, reliable results that guide treatment immediately. Walk-in diagnostic services at PACS include digital X-ray, EKG, blood work, and rapid pathogen testing.

Learn why it is worth it

Walk-In Diagnostic Care — No Long Wait, No ER Bill

Many patients delay diagnostic tests because of the inconvenience of separate appointments at separate locations. Combining diagnostics into your urgent-care visit saves time, reduces costs, and means treatment can start right away.

Our diagnostic services include digital X-ray imaging (chest, abdomen, spine, all extremities), 12-lead EKG, complete blood counts and metabolic panels, lipid and thyroid studies, A1C diabetes monitoring, urinalysis, rapid strep/flu/COVID/RSV testing, pregnancy testing, and STD panels. Send-out specialty testing is also available.

Walk in any time we’re open — with or without provider orders. We collect samples and capture imaging during your visit. Rapid in-office tests deliver results in minutes; lab and imaging results are reviewed by physicians and reported electronically. We can also receive orders from your primary-care provider for fast turnaround.

Service Overview

When diagnostics are part of your care, PACS Urgent Care is here to help. Our Alexandria and Ruther Glen/Ladysmith locations are equipped for on-site testing 7 days a week — fast results, expert review, and seamless coordination with your primary-care team.

Diagnostic services serve patients with provider orders looking for a more convenient location, walk-in patients needing same-visit testing as part of their evaluation, and individuals managing chronic conditions who need periodic monitoring without a primary-care appointment.

Most diagnostic services are covered by insurance when medically indicated. PACS Urgent Care offers transparent self-pay pricing — typically far less than hospital outpatient facilities. Imaging discs and electronic copies are available for your records or for forwarding to specialists.
