Hi, The inference of the blood report is there is some acute inflammation as suggested by the rise in polymorphonuclear leukocytes and ESR. You should get a clinical evaluation by a specialist to localize the source. Sometimes, asymptomatic bacteriuria of pregnancy can also cause such a picture. Culture of urine helps to identify. In such a case, assessment of the renal function is necessary even after delivery. Once the cause is located, appropriate treatment helps to relieve the condition. Hope this helps.
