About one in 20 women develop preeclampsia during pregnancy, which can be life-threatening to both moms and babies. However, it is difficult to diagnose because symptoms often mimic those of a normal pregnancy, such as swelling and headaches. Now a new innovation may help start treatment sooner by quickly identifying preeclampsia with a simple urine test. In a new study, researchers developed a fast and easy test to accurately diagnose the condition in just three minutes.
