Comparison of methods to identify significant proteinuria in pregnancy in the outpatient setting.
The efficacy of the albumin/creatinine ratio (ACR) measurement in detection of significant proteinuria when performed in a high-risk antenatal clinic was compared with automated dipstick, protein/creatinine ratio (PCR), and 24-hour urine protein measurements. Both the ACR (DCA 2000) and PCR were strongly predictive for the presence or absence of significant proteinuria, with positive likelihood ratios (LRs) of 27.4 and 31.6 and negative LRs of 0.0 and 0.1, respectively. Both the ACR (DCA 2000) and PCR are effective tests for both identifying and excluding significant proteinuria in the outpatient setting. The ACR (DCA 2000) has the advantage of providing an immediate result.
