Blood-Aid: A fast, new, cost effective and scalable way to reveal people's blood type. Blood-Aid was developed to address the fact that 40% of Brazilians don't know their blood type. This lack of knowledge holds Brazilians back from addressing some health precautions that are related to people's blood type as well as to answer to blood donation calls for specific blood types. PROBLEM: In Brazil, 40% of the population is unaware of their blood type. Knowing your blood type is important for several reasons. First, because some health factors are more common to specific blood types. Second, because when you do know your blood type you can donate when your specific blood type is in short supply and in need. OPORTUNITY: As a health diagnostics and integrated health system provider DASA Diagnostics decided to make the blood type information be readily available to the patients, and also invite them to learn more about what their blood type means for their health and also to sign up for alerts of when their specific blood type was in need of donations. IDEA: We developed a new kind of band-aid, which has a thin layer that in seconds when in touch with blood can detect what type of blood that is. Making the information of blood type readily available to everyone who comes for blood exams. This is Blood-Aid™. With that information, the patient is given specific literature developed by DASA concerning health traits of their specific blood type. Also, the patient is invited to sign up for alerts from the blood bank when their type of blood is in short supply and donations are needed.
