Giardia and Legionella Research Proficiency Testing to take place in July


Microbiological laboratories may signal interest in the pilot round to assess the accuracy of the techniques and inputs applied in the tests for the water matrix

To guarantee the absence of risk of contamination by disease-causing microorganisms, several microbiological controls are carried out in the water, including the Research by Giardia spp. and Legionella sp.

Controllab has an extensive scope of Proficiency Testing (PT) for microbiological analysis of water. In July, this scope will be expanded with the inclusion of new PTs by Giardia and Legionella.

The pilot round of the new PTs is composed of two items and the evaluation is made available by an individual report and a public profile of the results (without identifying the participants) for those registered. For Legionella, research and counting will be considered.

Those interested in participating in the pilot round, which will be sent free of charge on July 26, can sign up for participation on this link until the end of June.

All tests offered by Controllab follow the criteria of ABNT NBR ISO/IEC 17043. By participating in the PT, the laboratory will be able to evidence the accuracy of the analyzes and the reliability of the results issued in its routine.

The table below shows the PTs of microbiological analyzes for water already available. To find out more, access the Controllab website, contact us through the email or by phone +55 (21) 3891 9900 and WhatsApp (21) 98036-1592.

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.

Cgcre is signatory to the Mutual Recognition Arrangements of the International Laboratory Accreditation Cooperation (ILAC) and Interamerican Accreditation Cooperation (IAAC).

PEP 0003

Accreditation Cgcre/Inmetro - Proficiency Test Provider

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.
