Endoscopyīlood tests Laboratory Tests for Blood Disorders Doctors select tests to help diagnose blood disorders based on the person's symptoms and the results of the physical examination.

In VCUG, x-rays are taken after a radiopaque agent (dye) is inserted through a catheter inserted into the bladder. The tube that carries urine from the bladder out of the body (urethra) contains no bacteria. It can also identify when urine flows backward from the bladder into the ureters (called vesicoureteral reflux) and causes urinary tract infections Overview of Urinary Tract Infections (UTIs) In healthy people, urine in the bladder is sterile-no bacteria or other infectious organisms are present. This imaging test can identify blockages in those structures (for example, caused by birth defects). read more (VCUG), may be done to identify the site of obstruction, most often in children who have obstruction of the bladder or urethra. (See also Overview of the Urinary Tract.) X-rays are usually not helpful in evaluating. Other imaging tests, such as voiding cystourethrography Cystography and cystourethrography There are a variety of tests that can be used in the evaluation of a suspected kidney or urinary tract disorder. read more (MRI) is not as accurate as ultrasonography or CT, particularly for detecting kidney stones, but MRI may be used if it is important to avoid exposing the person to radiation and if the site of obstruction cannot be seen with ultrasonography. Magnetic resonance imaging Magnetic resonance imaging There are a variety of tests that can be used in the evaluation of a suspected kidney or urinary tract disorder. However, with newer CT scanners and new ways of using them, CT images can be obtained with much smaller doses of radiation. CT has traditionally involved exposure to significant doses of radiation. It is rapid and highly accurate, particularly at identifying stones. Computed tomography Computed tomography There are a variety of tests that can be used in the evaluation of a suspected kidney or urinary tract disorder.
