title: Enhanced urinalysis in the detection of asymptomatic bacteriuria in pregnancy.
abstract: BACKGROUND
  Detection and treatment of asymptomatic bacteriuria (ASB) in pregnancy is important to avert the attendant maternal and fetal morbidity. Other than urine culture, no other screening test is unequivocal.
  
  
  OBJECTIVE
  The use of enhanced urinalysis test to detect ASB in pregnancy was investigated.
  
  
  METHODS
  This was a prospective observational study which compared enhanced urinalysis with dipstick tests and urine culture. Clean catch midstream urine specimen was collected from 150 consecutive asymptomatic pregnant women. Tests of validity were used for comparison.
  
  
  RESULTS
  Enhanced urinalysis detected bacteriuria as much as urine culture (4% vs. 4.7%). Itwas 57.1% sensitive and 98.6% specific. It had a false negative rate of 42.9% and was 96.7% accurate when compared to urine culture. Enhanced urinalysis took 1-2 hours to be done and required skills to use the microscope and was more expensive than dipstick urinalysis.
  
  
  CONCLUSIONS
  The accuracy of enhanced urinalysis and its ability to detect ASB as much as urine culture connotes that it can be used to detect asymptomatic bacteriuria in pregnancy albeit only in secondary and tertiary health centres because of the cost and technicality involved.
