The effect of ethnicity on the performance of protein-creatinine ratio in the prediction of significant proteinuria in pregnancies at risk of or with established hypertension: an implementation audit and cost implications.

Our data suggest that a move from screening for proteinuria with a 24-h urine collection to screening with urine PCR is not appropriate for black populations. However, the move may lead to cost-saving if used in the white population with a PCR cut-off of 20.5.
