Strains Control (SC)


Controllab maintains the microorganisms for its laboratory.

To optimize time in the laboratory routine, Controllab ships certified strains that replace the passages. They are strains for prompt delivery, in the amount defined by the laboratory, from the selected microorganisms.

Why its important?

Certified strains confer more confidence and credibility in quality control, facilitating the process to comply with Anvisa / VISA standards, audits, accreditations and inspections.


  • Immediate delivery
  •  More agile processes
  •  More time to devote to analysing the results
  •  Maximization of infrastructure resources
  •  Less time with records for audits
  •  Cost optimization
  •  Ending of passage preparation


The professional stops routine the maintenance of the microorganism and gets more time to dedicate himself to the analyzing of the results.


In addition to reducing the high investments involved in acquisition and maintaining of the freezer at -70 ° C, the control strains reduce the number of tests required to maintain the microorganism.


Lyophilized strains are stored at 2 to 8 ° C, wich reduces the use of a freezer to -70 ° C (required for the proper maintenance of quality control strains).


The control strains accompany a certificate with phenotypic characteristics of the microorganism and summarize the number of records required in the audits.
  • Confidence in microbiological analysis

    Most of the strains supplied are first generation, or at most up to the third generation, avoiding mutations and phenotypic changes that can affect the results obtained in the analyzes. This definition of generations complies with the various standards for accreditation processes of laboratories and regulatory bodies in the area.
  • Credibility in Quality Control​

    The laboratory enrolled in the program uses reference strains certified with quality and international recognition. The lyophilized bacteria strains originate from the oldest culture collection in this category NCTC (National Collection of Type Cultures). ​​
  • Scheduled supply of lyophilized strains

    By joining the program, there is a continuous supply of the number of strains the laboratory needs, according to the schedule determined by the client. The laboratory also has immediate access to extraordinary purchases, due to the large and secure strain deposit of Controllab.
  • Productivity increase

    With the maintenance of microorganisms and the scheduled supply of strains, the teams involved in the analysis and acquisition processes gain more time to dedicate themselves to other routine activities.

Laboratory benefits

In addition to the benefits and advantages provided by the Program, Controllab provides strains certified by the NBR ISO 17034 standard, which are recognized as Certified Reference Material (MRC), the main quality standard within a laboratory’s analytical routine.

Controllab and UKHSA

Controllab, in its continuous search to provide the best solutions for laboratory quality control and attentive to laboratory challenges to remain sustainable and optimized resources, is expanding the initiatives in the microbiological area and begins these actions with the collaboration of the UKHSA – UK Health Security Agency. A UKHSA is the custodian of four unique collections, consisting of authentically preserved cell lines and microbial strains of known origin.

Among the collections, the NCTC (National Collection of Type Cultures) is the oldest of its kind – founded in 1920 – and has strains registered at the World Data Center for Microorganisms (WDCM)..

Authenticated reference strains and internationally recognized quality standards

The Strains Control Program is born with the commitment to deliver strains most of the 1st generation or up to the 3rd generation to laboratories. This commitment will help organizations to efficiently comply with the various regulations in the microbiological area for laboratory accreditation processes and regulatory agencies.

Authenticated reference strains are of paramount importance for the control of clinical diagnostic exams.By enrolling in the Strains Control Program, the laboratory tem acesso a um service with internationally recognized quality standards and immediate delivery.

Why should I join the Program STRAIN CONTROL?


Controls exam quality processes with authenticated strains


Perpetuates lab quality and credibility


Contributes to the efficiency of analysis processes


Accompanies certificates that prove the authenticity of the microorganism


Uses strains from internationally recognized culture collection


Promotes confidence in the microbiological processes

The laboratory enrolled in the Strains Control Program stops performing routine maintenance (continuous passages). Controllab provides this maintenance along with the selected strain certificate.

This practicality allows the laboratory to simplify the routine, gain more agility and reduce costs and time involved in testing and recording to ensure the quality of the peals in the process and to be audited.

See also the Gram and BAAR controls

This sustainability and quality is also available through Gram and BAAR controls How does it help in my laboratory? The strains of the Gram and BAAR controls are applied to the slides for positive and negative control of related microorganisms, which help laboratories to evaluate new batches of dyes / reagents. The controls consist of 15 slides of:
Smeared slides containing Staphylococcus aureus and Escherichia coli microorganisms..


Smeared slides containing Mycobacterium tuberculosis and Escherichia coli microorganisms.



Controllab offers complete solutions for quality and assertiveness of results. These solutions facilitate recognition for accreditation processes and regulatory bodies.
