What is the significance of red blood cells (RBCs) in urine?

• A. Indicates dehydration
• B. Suggests bleeding or kidney issues
• C. Signifies normal urine composition
• D. Shows high hydration levels

Answer: (B)

Red blood cells (RBCs) in urine are significant indicators of underlying health issues, particularly those related to bleeding or kidney problems. The presence of RBCs, a condition known as hematuria, can arise from various causes, including urinary tract infections, kidney stones, glomerulonephritis, or trauma to the kidneys. Each of these conditions indicates potential damage or pathology within the urinary system, making the detection of RBCs crucial for diagnosis and treatment. In contrast, the other choices do not accurately reflect the role of RBCs in urine analysis. For instance, while dehydration may concentrate urine, RBC presence is not a direct indicator of this condition. Similarly, the presence of RBCs does not signify normal urine composition or high hydration levels; normal urine typically contains very few to no RBCs.
