title: [Comparison of immunochromatographic tests Actim(®) Prom and Amnioquick(®) Duo for the rapid detection of premature rupture of membranes].
abstract: Premature rupture of membranes (PRM) affects 5 to 15% of pregnancies, leading to prematurity and neonatal infection. PRM can be identified by through various amniotic fluid proteins in vaginal secretions. The aim of this study is to compare two immunochromatographic tests based on the detection of insulin-like growth factor binding protein (IGFBP-1) and alpha-foeto protein (AFP) for one of the two tests in cervico-vaginal secretions. Two tests, Actim(®) Prom and Amnioquick(®) Duo were performed on 80 pregnant women with suspected PRM. Amnioquick(®) Duo allows the simultaneous detection of IGFBP-1 and AFP with an automated incubation and reading. The number of positive results is similar (Khi-deux = 0.173, p = 0.6773) for IGFBP-1 between the two tests and there is a good agreement (K = 0.621), with a proportion of negative results of 86%. The number of positive results for AFP is more important in comparison to IGFBP-1. Results positive/positive (Actim(®) Prom/Amnioquick(®)) for IGFBP-1 seems to be related to the time when tests have been performed, that is to say in the last weeks of pregnancy. In conclusion, both tests have similar performance, but there is a risk of false positive results with AFP, this can be explained by the presence of non-visible blood in samples. An automated incubation and reading allows a good reproducibility. Moreover, the computer data storage improve the post-analytical quality.
