  "text": "The use of the IF test as the principal screening test is recommended because of its proven robustness to achieve the required thresholds.\nWhen the IF test is used as the principal screening test and the IF reading is positive, the PCR or FISH test must be performed as a second screening test. When the IF test is used as the second screening test and the IF reading is positive, further testing according to the flow scheme is required to complete the analysis.\nPrepare separate positive control slides of the homologous strain or any other reference strain of C. m. subsp. sepedonicus, suspended in potato extract, as specified in Appendix 2, and optionally in buffer.\nNaturally infected tissue (maintained by lyophilization or freezing at -16 to -24 °C) should be used where possible as a similar control on the same slide.\nAs negative controls, use aliquots of sample extract which previously tested negative.\nUse multiwell microscope slides with preferably 10 windows of at least 6 mm diameter.\nTest control material in an identical manner as the sample(s).",
