The CRM Qualitative Reference Cultures, derived from the European NCTC culture collection, obtains user recognition due to good recovery and growth of microorganisms

In the routine of the analysis laboratories, the reference strains are fundamental for the quality control of the inputs used in the clinical and veterinary diagnostic exams, in the microbiological analysis of food, water, pharmaceutical products and the environment. They are also of great importance for carrying out studies to validate analytical methods and determine measurement uncertainty.

In its continuous search to provide the best solutions in laboratory quality control, Controllab has partnered with PHE – Public Health England. This initiative made it possible for Brazil and other Latin American countries to have immediate access to the oldest bacterial collection in the world – NCTC (National Collection of Type Cultures) – founded in 1920.

Initially, the production of control strains was made possible and then the materials obtained the seal of ABNT NBR ISO 17034. Today, there are more than 60 strains recognized as Certified Reference Material (CRM), available for prompt delivery or scheduled monthly in the quantity defined by the laboratory. These strains help the processes to comply with the requirements of NBR ISO/IEC 17025 regarding the quality control of the results.

The lack of knowledge of other collections of cultures equivalent to the American, initially, caused hesitation in laboratories to adopt strains from other origins. But, there are currently 802 collections of cultures in 78 countries and regions* registered in the WDCM (World Data Center for Microorganisms), an international database that groups strain into a unique system of identifiers, facilitating the crossing of information about recommended reference strains for use in quality assurance. In it, it is possible to verify that the same strain has a different designation in each culture collection. For example, the strain Escherichia coli NCTC 11954 is also designated ATCC 35218, CIP 102181, DSM 5923, CCUG 30600, CECT 943 depending on the culture collection.

Users who did the experimentation then included the CRM Qualitative Reference Cultures in their routine, from the NCTC. The cultures show good recovery and growth of microorganisms, contributing to the main validations: test for detection of microorganisms, antibiograma, alternative methods, new equipment, microbiological inputs (culture media), etc. They give more confidence and credibility to quality control, facilitating the process of meeting standards, laws, audits, accreditations and inspections.

The benefit of the initiative reaches, in addition to Brazil, countries such as Argentina, Bolivia, Chile, Colombia, Ecuador, Paraguay, Peru, Suriname, Uruguay and Venezuela. Access the Controllab website and learn more about the strains available at the Qualitative Reference Cultures.

PRM 0009

Accreditation Cgcre/Inmetro - Certified Reference Material Producer

Controllab has been accredited as a Certified Reference Material Producer (MRC) since 2016 by Inmetro’s General Coordination for Accreditation (CGCRE), under the PMR 0009 number. The assessment of this conformity is carried out according to the requirements established in ABNT NBR standards ISO 17034 and Inmetro, thus ensuring competence for the production of MRCs, according to the Scope of Accreditation.

CAL 0214

Accreditation Cgcre/Inmetro - Calibration Laboratory

In December 2002, the Calibration Laboratory was accredited by Inmetro’s General Coordination for Accreditation (CGCRE). With this recognition, it became an integral part of the Brazilian network of accredited laboratories, under nº214. Since then, it is periodically evaluated for the maintenance and/or extension of accreditation.

PEP 0003

Accreditation Cgcre/Inmetro - Control Laboratory

In September 2011, Controllab was accredited by Inmetro’s General Coordination for Accreditation (CGCRE) as a proficiency test provider, under nº PEP0003. Initially as part of a pilot project by Inmetro, this accreditation was based on ILAC G13: 2007 and included several clinical and hemotherapy tests. In the periodic evaluations of this accreditation, new segments and tests are included and the evaluation is now conducted according to ABNT NBR ISO/IEC 17043.

This accreditation attests to Controllab’s technical competence to develop and conduct proficiency tests in accordance with international requirements and enables it to be recognized in other countries, in accordance with mutual recognition agreements signed by Brazil in Mercosur, the Americas and Europe.
