Is blood and urine the same thing?

Hematuria is

a common term for patients who find that urine is light red or contains blood clots during urination. It is clinically called hematuria. In addition, hematuria can be divided into macroscopic hematuria and microscopic hematuria. Macroscopic hematuria is that the urine is dark and red, while microscopic hematuria is that the patient's urine is normal in color, but there are more than 3 red blood cells in the urine after centrifugation. Regardless of whether the patient has gross hematuria or microscopic hematuria, further imaging and laboratory tests should be performed to determine the cause and treat it.
