Each year, 6.3 million pregnant women and newborns die from pregnancy and childbirth complications. In many developing countries, little or no prenatal care is administered and diseases are not discovered until it is too late. Currently, the most common way to screen for preeclampsia and related complications is with a 50-cent dipstick. However, this is too expensive to be widely used in developing countries. A group at Johns Hopkins University has developed the Antenatal Screening Kit to provide an even lower-cost alternative. The kit includes a set of different colored markers and filter paper. Adding a single drop of urine to a line drawn on a piece of filter paper can detect various diseases through color changes. Each marker costs only $1 and can be used up to 400 times.
