What medical term describes the presence of blood in urine?

• A. Anuria
• B. Cystitis
• C. Hematuria
• D. Hemoglobinuria

Answer: (C)

The term that describes the presence of blood in urine is "hematuria." This term is derived from the Greek "haima," meaning blood, and "ouron," meaning urine. When clinicians refer to hematuria, they are indicating that there is an abnormal amount of red blood cells present in the urine, which can be identified through urinalysis. It can be a symptom of various medical conditions affecting the urinary system, such as infections, stones, or trauma.

"Anuria" refers to a condition where there is no urine output, while "cystitis" is an inflammation of the bladder, often due to infection, which may lead to symptoms like painful urination but does not specifically denote the presence of blood. "Hemoglobinuria" describes a condition where hemoglobin is present in the urine, which can result from conditions that cause the breakdown of red blood cells, but it is distinct from hematuria, as it does not specifically involve intact red blood cells. Thus, hematuria is the accurate term for blood in urine, making it the correct answer.
