Palang Merah Remaja adalah Relawan masa depan. Ada 3 tingkatan dalam PMR yaitu PMR Mula (setingkat Sekolah Dasar/Madrasah Ibtidaiyah),PMR Madya(setingkat SMP/Madrasah Tsanawiyah) dan PMR Wira (setingkat SMA/SMK/Madrasah Aliyah). Tri Bhakti Palang Merah Remaja menjadi pedoman PMR dalam melaksanakan kegiatan sosial kemasyarakatan, TRI BHAKTI PMR adalah 1. Berbhakti kepada Masyarakat, 2. Mempertinggi keterampilan, memelihara kebersihan dan kesehatan, 3. Menjalin persahabatan nasional dan internasional.
Itu memang hal idealnya, akan tetapi melihat kondisi dan perkembangan PMI saat ini cukup memprihatinkan. Satu contoh adalah masalah persediaan darah di PMI yang seringkali kosong dan permintaan darah dengan biaya yang cukup mahal.
