Tests and diagnosis
A CT scan is an imaging test that uses X-rays to produce detailed images of the inside of your body.
MRI uses a magnetic field and radio waves to create detailed images of the organs and tissues within your body.
Ultrasound imaging uses high-frequency sound waves to create images of structures in your body.
Urinalysis can be used to assess your overall health, detect a wide range of disorders, or monitor a medical condition or treatment.
