Urine Congo red test for the detection of preeclampsia in pregnant women presenting with suspected preeclampsia

OBJECTIVES: To determine the predictive performance of the urine Congo red point-of-care test for the identification of preeclampsia in women presenting with suspected preeclampsia.

METHODS: A prospective multi-center cohort study was conducted to include women with suspected preeclampsia (n = 244). The urine Congo red test was determined (score range 1-8). The diagnosis of preeclampsia was based on criteria proposed by The American College of Obstetricians and Gynecologists. The primary outcome was the predictive performance (sensitivity, specificity, negative and positive predictive values, as well as likelihood ratios) of the Congo red kit test for the diagnosis of preeclampsia.

RESULTS: Fifty-four percent (131/244) of women with suspected preeclampsia subsequently developed preeclampsia. The sensitivity and specificity of the urine Congo red test were 49.6% and 94.7%, respectively, when using a cutoff for Congo red ≥4. The test had a significant positive correlation with the level of urine protein (Pearson correlation 0.61, p-value <.01). Intra- and inter-observer reliabilities were good (intra-class correlation coefficient and Cohen's kappa coefficient of 0.88 and 0.75, respectively; p < .01).

CONCLUSION: The urine Congo red kit test has a high positive predictive performance for the identification of preeclampsia with high reproducibility. This test may be used as a bed side test to rule-in the diagnosis of preeclampsia in women presenting with suspected preeclampsia.
