On-Site Diagnostics

Diagnostic & Imaging Capabilities

Some emergencies need more than an examination. Having imaging and laboratory services inside the facility means the emergency team can evaluate many conditions in one visit, without sending you to a separate outpatient center.

CT Scan

CT imaging may help evaluate certain head, chest and abdominal emergencies when ordered by the physician.

Digital X-Ray

X-rays help assess possible fractures, certain chest conditions and other injuries.

Ultrasound

Ultrasound may be used for selected abdominal, pelvic and other evaluations when clinically appropriate.

On-Site Laboratory

Lab testing supports evaluation of infection, dehydration, cardiac concerns and other conditions.

EKG & Cardiac Testing

An EKG and related testing may be used for chest pain, palpitations or other heart-related symptoms.

Testing is selected based on your symptoms, examination and the physician's assessment.

When medically appropriate, treatment may also include IV fluids and medications, wound care, splinting, breathing treatments and cardiac monitoring. Testing and treatment are always based on the physician's assessment.

  • A list of current medications
  • Relevant medical history or allergies
  • Emergency contact information
  • For a child, their immunization or medication details if handy

When to Call 911

Emergency medical responders can begin care on the way to the hospital.
