Proficiency Testing for the detection of anti-Toxoplasma IgG in swine serum samples: aim, instructions and procedure

The EURLP organizes a proficiency testing for laboratories performing serological tests on the presence of anti-Toxoplasma IgG in swine serum samples. According to the ISO/IEC 17043:2010 standard, this proficiency testing is aimed to establish the effectiveness and comparability of the serological tests, employed by participant laboratories in their routine work.
Who can participate to the PTs. All National Reference Laboratory (NRL) for parasites from EU member states or associated countries.
Aim of the PTs. Detection of anti-Toxoplasma IgG in swine serum samples.
Procedure to analyse the panel of samples. A panel of 7 serum samples is delivered to each participant. Each sample consists of an aliquot of single serum sample collected from naturally Toxoplasma gondii infected swine (positive) and from Toxoplasma gondii free swine (negative). Samples shall be analyzed within 7 days after the delivery to the lab by one of the serological tests based on the detection of anti-Toxoplasma IgG . Each laboratory should choose the test routinely used in the lab.
Criteria for the result evaluation. The participating laboratory has to indicate the positivity or negativity of each tested samples, together with the IgG titer found in each positive sample. Each serum sample is reported as “correctly classified” or “incorrectly classified”. Final evaluation is considered as “positive” if all samples are correctly classified and “negative” in all the other cases. The result evaluation is qualitative, IgG titers will be considered as additional information on the reliability of the tests used by participants.
Report. The EURLP provides both an Individual PT Report including the results and comments and/or recommendations made by EURLP and a Final PT report presented during the annual NRL workshop and afterwards published on the EURLP web site. To guarantee confidentiality, the individual PT report is available only to the participant lab, and in the final PT report, only lab codes are displayed.

Detailed instructions and procedure to participate to the Proficiency Testing for the detection of anti-Toxoplasma IgG in swine serum samples, are reported in the .pdf documents you can download from below.
