Answer:
Urine refrigeration preservation maintains the sample in the ACS chemical analysis, cellularity and bacteriuria
Step-by-step explanation:
Tests with high diagnosis and prognostic importance in clinical practice include urinary irregular constituents and sediment (ACS). If it is not possible to analyze ACS within two hours of processing, the sample must be retained to prevent pre-analytical interferences. Cooling is due to its economic productivity the most commonly used technique. In comparison, relative to chemical preservation, it poses fewer discomforts.
