Desain penelitian adalah cross sectional dengan pendekatan kuantitatif. Responden adalah petugas laboratorium klinik peserta uji profisiensi. Sampel penelitian berupa total populasi sebanyak 77 laboratorium. Pengumpulan data dilakukan dengan kuesioner dari melihat hasil evaluasi kegiatan pengendalian mutu eksternal laboratorium kesehatan provinsi Jawa Barat tahun 2007.
