What is the standard method for confirming hematuria?

The standard method for confirming hematuria is microscopic examination of the urine. When hematuria, which is the presence of blood in the urine, is suspected based on symptoms or initial tests, a more definitive assessment is required. Microscopic examination allows for the evaluation of urine sediment, where red blood cells can be directly counted and assessed for abnormalities. This examination can differentiate between simple hematuria and more complex issues, such as urinary tract infections or kidney stones, providing critical diagnostic information.

While chemical urinalysis can indicate the presence of blood, it does not confirm hematuria as effectively as microscopic examination, because it may produce false positives due to other factors within the urine. Visual observation can identify blood or discoloration but lacks the objectivity and detail of microscopic assessment. CT scans are useful in identifying the underlying causes or conditions related to hematuria but are not used to confirm its presence directly. Thus, for accurate diagnosis and confirmation, microscopic examination is the preferred method.
