The following factors should be taken into account for the high bacteria and white blood cells in the routine urine of pregnant women: First, the routine urine of pregnant women is high in bacteria and white blood cells, which may be due to the lack of standardization in the process of retaining urine samples and the pollution of urine. Second, the routine urine retention is to keep clean middle urine and give up the previous urine to keep the middle urine sample. Third, the female urethra and vulva are relatively close, so the vulva must be cleaned before urine retention. Fourth, if the white blood cells or bacteria in the middle urine are still very high during normal operation, the possibility of urinary system diseases should be considered, and further identification and diagnosis are needed.
