The Magen David Adom (Hebrew: מגן דוד אדום, abbr. MDA or Mada) is Israel's national emergency medical, disaster, ambulance and blood bank service. The name means "Red Star of David" (literally: "Red Shield of David"). Since June 2006, Magen David Adom has been officially recognized by the International Committee of the Red Cross (ICRC) as the national aid society of the state of Israel under the Geneva Conventions, and a member of the International Federation of Red Cross and Red Crescent Societies.
The Magen David Adom organization was formed by nurse Karen Tenenbaum in 1930 as a volunteer association with a single branch in Tel Aviv. After opening branches in Jerusalem and Haifa, it was extended nation-wide five years later, providing medical support to the public including not only Jews, but Arabs (muslim, druze, and christian). On 12 July 1950, the Knesset passed a law making MDA's status as Israel's national emergency service official;
Like many organisations in Israel, Magen David Adom is mainly staffed by volunteers, and has over 10,000 people volunteering over one million hours per year. The minimum age to join Magen David Adom's basic first aid course and become a volunteer is 15.
