Classification by the extent of hematuria
- Dipstick hematuria: Detection of hemoglobin within red blood cells using reagent strips in macroscopically normal urine.This describes the use of reagent strips to detect blood chemically within urine.
- Microscopic hematuria: Defined as the presence of more than two to five red blood cells per high powered field within macroscopically normal urine on a properly collected urinary specimen in the absence of an obvious benign cause.[1]
- Macroscopic hematuria: Defined as the presence of blood in urine that is visible with naked eye.
Classification by the visibility of hematuria
- Visible hematuria: Visible hematuria can be visualized with the naked eye and is also known as frank, gross or macroscopic hematuria. Visible hematuria is more likely to be associated with malignancy.
- Initial hematuria: May indicate urethral pathology
- Terminal hematuria: Hematuria at the end of the stream that comes from the proximal urethra (bladder neck/prostate).
- Complete hematuria: Hematuria throughout the entire stream suggests bladder, ureteric or renal pathology.
- Non-visible hematuria: Non-visible hematuria encompasses dipstick and microscopic hematuria.[2]
Classification by the duration of hematuria
- Transient hematuria: A single urinalysis with hematuria is common and can result from menstruation, viral illness, allergy, exercise, fever, or mild trauma.
- Persistent or Significant hematuria: >3 RBCs/HPF on three urinalyses, a single urinalysis with >100 RBCs, or gross hematuria.
