WHO COLLABORATING CENTRE – ANTIMICROBIAL RESISTANCE
  
 
 
EXTERNAL QUALITY ASSURANCE SYSTEM (EQAS) 
 
Participation in internal and external quality assurance systems is a useful tool for production of reliable laboratory results of consistently good quality.
 
However, a WHO survey of antimicrobial resistance surveillance capabilities in 1995 determined that more than 50% of laboratories performing susceptibility testing of Salmonella isolates did not participate in any formal system of quality assurance.
 
Descriptions of the EQAS
 
The National Food Institute, a WHO Collaborating Centre and one of the coordinating agencies of WHO GFN, is responsible for conducting the WHO GFN EQAS for Salmonella serotyping and antimicrobial susceptibility testing (AST) methods.
 
Included is also the option to take part in Shigella serotyping and AST, Campylobacter identification and AST as well as identification of an unknown enteric bacteria. This programme is developed specifically for national reference laboratories participating in the WHO GFN, and runs annually.
 
Laboratories participating in the EQAS receive the strains by mail. The strains should be tested by the methods routinely used in the laboratory and the results should then be submitted to DTU Food through a web-based database (password-protected). Immediately upon receiving the results, an evaluation report will be generated for you.
 
Full anonymity is ensured; only DTU Food and the WHO GFN Regional Centre in your region will be given access to your results. When the results of each cycle of the EQAS have been evaluated, a final summary report is prepared and distributed to all GFN laboratories.
 
Various aspects of the proficiency test scheme may from time to time be subcontracted. When subcontracting occurs it is placed with a competent subcontractor and the National Food Institute is responsible to the scheme participants for the subcontractor's work.

Eligibility to participate
 
The WHO GFN EQAS is open to all national reference laboratories in the Global Foodborne Infections Network.
 
Fees 
 
Participation in the EQAS is free of charge for laboratories participating in the GFN. However, if your country claims taxes or customs fees this will be on the participating laboratory's expenses. 
 
How to participate 
 
Participants who wish to sign up to the WHO GFN EQAS do so through a web-based database (open until May each year). Members of the Global Foodborne Infections Network will receive an invitation to sign up each year when the sign-up database opens. The sign-up for the 2014 iteration has ended.   
 
If you are a national reference laboratory and wish to take part in the EQAS but are not part of WHO GFN, you must first join the WHO GFN. Via this link you find the sign-up form: http://thor.dfvf.dk/pls/portal/url/page/gss/gfn_sign_up
