Hematuria severity based on detection method
| Hematuria severity | Detection method Standard microscopy | Automated assay | Automated urine particle analyzer (for the detection method) |
|---|---|---|---|
| Minimal (1) | <5 | Negative | <20 RBC/microliter |
| Mild (2) | 5 ≤ 25 | 1+ | 201–00 RBC/microliter |
| Moderate (3) | 25 ≤ 50 | 2+ | >100 RBC/microliter |
| Severe (4) | >50 | 3+ | >100 RBC/microliter |
Standard microscopy: centrifuged (2000X) urine specimen resuspended after supernatant removal and examined at microscopy at x400 high power microscopic field (RBC/HPMF); Automated assay: dipstick + Automated urine particle analyzer (UF-5000) a third generation automated flow cytometry analyzer for urine sediment analysis [34].
