Asymptomatic bacteruria is when there are elevated bacteria levels in urinalysis or there is culture growth but there are no symptoms thereby asymptomatic. Although asymptomatic, asymptomatic bacteruria is a form of urinary tract infections but only needs to be treated if the urinary tract infection is symptomatic or complicated such that in pregnancy, those with unstable comorbidities such as diabetes, and those with structural anatomic urinary tract defect i.e. vesicoureteral reflux.
