Diagnostics For All will develop a sensitive, low-cost, rapid, paper-based microfluidic diagnostic test to screen pregnant women for anemia, HIV, HBV, and syphilis, from one drop of blood. This antenatal care (ANC) test panel will ensure that women who attend ANC at least once are tested for the most critical diseases and provided results on the spot. This ANC panel could improve maternal and child health outcomes for up to 31 million pregnant women in the developing world and their children.
