A 5-mL urine specimen is submitted for routine urinalysis and is analyzed immediately.
The SG of the sample is 1.020 and the pH is 6.5.
The dry reagent strip blood test is a positive, and the microscopic exam shows numerous RBCs and WBCs.
The leukocyte esterase reaction is positive and the microscopic examination shows bacteria and WBC casts.
