The PNCQ – National Quality Control Program – started in 1976, during the 5th Brazilian Congress of Clinical Analyzes in Belo Horizonte – MG, where a freeze-dried serum was distributed to some laboratories for certain dosages in biochemistry.

Subsequently, other control samples were sent, with no defined frequencies. From then on, the PNCQ was administered by SBAC, Brazilian Society of Clinical Analyzes, now directly or outsourced, when in 1985, SBAC decided definitively for the management of the PNCQ, until it was transformed into an independent legal entity in 1993, giving beginning of a phase of growth and modernization of the Program, making it the largest and best existing in the country, with the introduction of new materials for External Control, computerized spreadsheets for insertion of results in the PNCQ Data Processing Center, through the Internet, providing speed in evaluating the responses of its customers.

Today, the PNCQ is proud to be the largest Proficiency Testing Provider of national size and to represent Brazil in several international scientific associations, in addition to having a considerable adhesion of Clinical Laboratories, both national and international, which is being processed continuously.
