The Clinical Laboratory Improvement Act began in the late 1960's when problems arose in the cytology laboratories that read PAP smears. The personnel in these laboratories were overworked and had a very high error rate. In 1967, the Clinical Laboratory Improvement Amendment was passed and the first laboratory regulations were born. These regulations primarily covered independent and hospital laboratories.
