Paper devices detect malaria better in Ghana

Researchers have developed paper-based devices that accurately detect malaria in asymptomatic individuals, outperforming existing methods in field tests in Ghana. This advancement could significantly aid in malaria elimination efforts. The devices use cheap paper strips to facilitate chemical reactions with blood samples, identifying malaria-specific antigens. In a study, these devices showed 96.5% sensitivity, significantly higher than microscopy and rapid diagnostic tests, and comparable to PCR tests. The technology allows for remote testing, providing results in about 30 minutes and enabling easy transport of samples for further analysis. The researchers are now discussing implementation with the Ghanaian government and adapting the devices for other diseases.
