The use of the IF test as the principal screening test is recommended because of its proven robustness to achieve the required thresholds.
When the IF test is used as the principal screening test and the IF reading is positive, the Isolation, 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.
Standardised positive and negative control materials available for use with this test are listed in Appendix 3.
Use multiwell microscope slides with preferably 10 windows of at least 6 mm diameter.
Test control material in an identical manner as the sample(s).
