Pathology is a medical subfield with a focus on the diagnosis of disease. Medical professionals who become pathologists often have background knowledge in several different areas of medicine, as this knowledge is helpful when it comes to diagnosis. Pathologists generally test for disease by analyzing tissue, body fluid, and cell samples. In this way, these doctors can diagnose problems caused by parasites, pathogens, and even non-infectious causes. This work can help other physicians make the proper treatment recommendations.

A urologist is a health professional who studies and treats disorders of the urinary tract. Urologists can conduct tests, perform surgery, and help resolve any issues that a patient may be having with urination. Urologists treat the kidneys, ureters, bladder, urethra, and adrenal glands. They can also treat some male reproductive organs that are connected to the urinary tract.
