DNA from the animal to be tested is always the basis for PCR detection. An EDTA blood sample (0.5 – 1 ml) is best suited for purifying the DNA, as a large amount of cell material from the animal is available here.
In principle, it is also possible to use two buccal swabs. For this purpose, a sterile cotton swab is rubbed vigorously on the inside of the cheek. The swab should then be dried to avoid mould and sent in a tube without medium (no liquids or agar).
When using swabs, please ensure that the animal in question has not eaten for 1-2 hours and has not been in contact with other animals to avoid contamination that could affect the result of the test.
