R4H supports the Ministry of Health (MOH) by facilitating the transportation of clinical samples and laboratory results between health facilities and molecular labs. This service includes the transport of dried blood spots for HIV testing, sputum samples for tuberculosis diagnosis, and other disease-related samples. R4H couriers use the Sample Transport CommCare application on mobile tablets to document information regarding the samples and their results while in transit. The initiative also emphasizes mental health as a key focus area.
