Difco™ QC Antigens Salmonella O are used in the quality control testing of Difco Salmonella O Antisera by slide agglutination tests. Difco™ QC Antigens Salmonella O are used in the quality control testing of Difco Salmonella O Antisera by slide agglutination tests. The use of Difco Salmonella O Antisera in the serologic identification of Salmonella requires the use of quality control test suspensions to verify that the antisera are performing as expected. Most laboratories are required to test antisera with positive and negative controls prior to use.1,2 Difco QC Antigens Salmonella O are chemically stabilized and inactivated suspensions of known strains of the genus Salmonella designed for use as homologous controls for testing the efficacy of the Salmonella typing antisera employed in routine laboratory procedures. The chart below includes the Difco QC Antigens Salmonella O recommended as the homologous (positive) control antigen. The homologous control antigen has in common certain identifying antigen(s) with the antiserum. The Difco QC Antigens Salmonella O may also be used to demonstrate a heterologous (negative) control reaction. For use as a negative control, use a QC Antigen Salmonella that contains antigens unrelated to those in the homologous control.
Note: For a complete and current explanation of the classification of Salmonella, consult appropriate references.3-5 The use of Difco Salmonella O Antisera in the serologic identification of Salmonella requires the use of quality control test suspensions to verify that the antisera are performing as expected.

Quality control requirements must be performed in accordance with applicable local, state and/or federal regulations or accreditation requirements and your laboratory's standard Quality Control procedures. It is recommended that the user refer to pertinent NCCLS guidance and CLIA regulations for appropriate Quality Control practices.
When used as described (see PROCEDURE) each vial of antigen is sufficient for 20 slide tests. Difco QC Antigens Salmonella O are preserved with 0.5% phenol USP (v/w) except for Difco QC Antigen Salmonella O Group Vi which contains 0.01% thimerosal (v/w). For in vitro Diagnostic Use. The Packaging of This Product Contains Dry Natural Rubber. Observe aseptic technique and established precautions against microbiological hazards throughout all procedures. After use, specimens, containers, slides, tubes and other contaminated material must be sterilized by autoclaving. Directions for use should be followed carefully. Difco QC Antigens Salmonella O are not to be used for immunization of man or animals. | ||||||||||||||||||||||||||
