  "text": "In Annex X, Chapter C, to Regulation (EC) No 999/2001, point 4 is replaced by the following:\n‘4.\nRapid tests\nFor the purposes of carrying out the rapid tests in accordance with Articles 5(3) and 6(1), the following methods shall be used as rapid tests for the monitoring of BSE in bovine animals:\nimmuno-blotting test based on a Western blotting procedure for the detection of the Proteinase K resistant fragment PrPRes (Prionics-Check Western test),\nchemiluminescent ELISA test involving an extraction procedure and an ELISA technique, using an enhanced chemiluminescent reagent (Enfer test & Enfer TSE Kit version 2.0, automated sample preparation),\nmicroplate based immunoassay for the detection of PrPSc (Enfer TSE Version 3),\nsandwich immunoassay for PrPRes carried out following denaturation and concentration steps (Bio-Rad Te-SeE test),\nmicroplate based immunoassay (ELISA) which detects Proteinase K resistant PrPRes with monoclonal antibodies (Prionics-Check LIA test),\nconformation-dependent immunoassay, BSE antigen test kit (Beckman Coulter InPro CDI kit),\nchemiluminescent ELISA for qualitative determination of PrPSc (CediTect BSE test),\nimmunoassay using a chemical polymer for selective PrPSc capture and a monoclonal detection antibody directed against conserved regions of the PrP molecule (IDEXX HerdChek BSE Antigen Test Kit, EIA),\nmicroplate based chemiluminescent immunoassay for the detection of PrPSc in bovine tissues (Institut Pourquier Speed’it BSE),\nlateral flow immunoassay using two different monoclonal antibodies to detect Proteinase K resistant PrP fractions (Prionics Check PrioSTRIP),\ntwo-sided immunoassay using two different monoclonal antibodies directed against two epitopes presented in a highly unfolded state of bovine PrPSc (Roboscreen Beta Prion BSE EIA Test Kit),\nsandwich ELISA for the detection of Proteinase K resistant PrPSc (Roche Applied Science PrionScreen),\nantigen-capture ELISA using two different monocloncal antibodies to detect Proteinase K resistant PrP fractions (Fujirebio FRELISA BSE post-mortem rapid BSE Test).\nFor the purposes of carrying out the rapid tests in accordance with Articles 5(3) and 6(1), the following methods shall be used as rapid tests for the monitoring of TSEs in ovine and caprine animals:\nconformation-dependent immunoassay, BSE antigen test kit (Beckman Coulter InPro CDI kit),\nsandwich immunoassay for PrPRes carried out following denaturation and concentration steps (Bio-Rad Te-SeE test),\nsandwich immunoassay for PrPRes carried out following denaturation and concentration steps (Bio-Rad Te-SeE Sheep/Goat test),\nchemiluminescent ELISA test involving an extraction procedure and an ELISA technique, using an enhanced chemiluminescent reagent (Enfer TSE Kit Version 2.0),\nmicroplate based immunoassay for the detection of PrPSc (Enfer TSE Version 3),\nimmunoassay using a chemical polymer for selective PrPSc capture and a monoclonal detection antibody directed against conserved regions of the PrP molecule (IDEXX HerdChek BSE-Scrapie Antigen Test Kit, EIA),\nmicroplate based chemiluminescent immunoassay for the detection of PrPSc in ovine tissues (POURQUIER’S-LIA Scrapie),\nimmuno-blotting test based on a Western blotting procedure for the detection of the Proteinase K resistant fragment PrPRes (Prionics-Check Western Small Ruminant test),\nmicroplate based chemiluminescent immunoassay for the detection of Proteinase K resistant PrPSc (Prionics Check LIA Small Ruminants).\nIn the case of all tests, sample tissue to which the test is to be applied must comply with the manufacturer’s instructions for use.\nThe producer of the rapid tests must have put in place a quality assurance system, approved by the Community Reference Laboratory (CRL) that ensures that the test performance does not change. The producer must provide the test protocol to the CRL.\nChanges to rapid tests and to test protocols may be made only after prior notification to the CRL and provided that the CRL finds that the change does not alter the sensitivity, specificity or reliability of the rapid test. That finding shall be communicated to the Commission and to the national reference laboratories.’",
