Ultrafast CT Scan
An ultrafast CT scan is an imaging test that uses X-rays and a computer to look at your heart. The scan takes pictures very quickly. It gives your healthcare provider many details about your heart that other imaging tests cannot.
Upper GI Endoscopy
An upper GI endoscopy or EGD (esophagogastroduodenoscopy) is a procedure to diagnose and treat problems in your upper GI tract (gastrointestinal tract).
Upper Gastrointestinal Series
An upper gastrointestinal series is an imaging test of your esophagus, stomach, and first part of your small intestine (duodenum). The test is done with X-rays after you swallow a special beverage. The beverage contains either contrast or a powder called barium.
Uterine Artery Embolization
Uterine artery embolization is a procedure to get rid of noncancerous tumors in the uterus (uterine fibroids). It does not use major surgery, so you may recover faster. You also may not need to stay in the hospital.
Urine Flow Test
A urine flow test calculates the speed of urine flow over time. It may be used to check how the bladder and sphincter are working. For this test, you will urinate into a special funnel that is connected to a measuring instrument. The instrument calculates the amount of urine, rate of flow in seconds, and the length of time until all urine has been passed. This information helps evaluate how well the lower urinary tract is working. It also helps figure out if there is a blockage of normal urine outflow.
Uniparental Disomy
This test is used to see if a child has certain chromosome changes.
Urea Nitrogen Clearance (Urine)
This test measures the amount of urea nitrogen in your urine. The test can help diagnose kidney problems.
Uric Acid (Blood)

Uric Acid (Urine)
This test is used to find out whether you have gout. It can also be used to monitor you during cancer treatment and to check your urine after you've had a kidney stone.
