Problem being addressed[edit | edit source]
Accurate, low-cost, point-of-care diagnostics for pregnant women and newborns are severely lacking in resource-limited rural settings. This is especially true where there are shortages of trained health workers to administer and evaluate diagnostic tests for life-threatening conditions such as pre-eclampsia. Accurate and low cost diagnostics for hypertension (pre-eclampsia) and high blood glucose (gestational diabetes) could help women get access to appropriate life-saving care.
Detailed description of the solution[edit | edit source]
Two accurate, low-cost (<$0.10) postage stamp-sized paper-based diagnostics for expecting mothers and newborns will be used to detect – and enable proper treatment of – (i) anemia and hyper/hypoglycemia and (ii) hypertensive disorders. These point-of-care diagnostics require only a drop of blood or urine and require no additional steps beyond applying the sample. This means that they can be utilized by minimally-trained individuals in communities or clinics in rural settings to prevent unnecessary deaths during pregnancy and childbirth and improve the health of mothers and newborns through early detection of high-risk pregnancies and better patient management.

Diagnostics for All, 790 Memorial Drive, Suite 104, Cambridge, MA 02138. Home page found here.
- Manufacturer location:
Currently manufactured in Cambridge, MA, but creators emphasize that the "simple process enables these tests to be manufactured in-country and sold by local manufacturers and distributors for profit while still remaining affordable."
When and where it was tested/implemented[edit | edit source]
Currently in development.
Funding Source[edit | edit source]
Awarded Saving Lives at Birth Grand Challenge, July 2011, which is sponsored by USAID, the Government of Norway, the Bill & Melinda Gates Foundation, Grand Challenges Canada, and The World Bank.
