BMI: body mass index. The urinary microscopy WBC : high magnification, urine sediment white blood cell count. WBC (+): urinary sediment microscopy counts of 5—10/HP. WBC (++): urinary sediment microscopic counting 10—15/HP. WBC (+++): urinary sediment microscopic counting 15—20/HP. WBC (++++): urinary sediment microscopic counting >20/HP.
