MICROSCOPIC EXAMINATION
Microscopic is performed based on physical and chemical
results
Macroscopic Screening / Chemical Sieving
Color, clarity, blood, protein, nitrite, leukocyte esterase, and possibly glucose
Macroscopic Screening / Chemical Sieving
Special populations: pregnant women; pediatric, geriatric, diabetic, immunocompromised, renal patients
Macroscopic Screening / Chemical Sieving
Sediment Standardization
STANDARDIZATION OF SEDIMENT PREPARATION
- Requested by the physician
- Laboratory-specified population
- Any abnormal physical or chemical result
- Laboratory criteria are programmed into automated instrumentation
