If a pregnant woman has a urine test during pregnancy that suggests high levels of bacteria, or white blood cells, inside the urine, there are several conditions that generally need to be considered: first, urinary tract infections, women have a relatively short urethra, and if they get a urethritis during pregnancy, it can cause an increase in white blood cells, as well as frequent and urgent urination, a condition that requires treatment. Second, if there is a kidney disease, like nephritis, it will also lead to leukocytosis. Third, it can also lead to leukocytosis. Pregnant women have more leukorrhea, and if the urine is mixed with leukorrhea inside, it will also lead to leukocytosis. In this case, first of all, we should pay attention to hygiene, and we should review it at the right time.
