Does any medication interfere with the diagnostic test?

Corticoids:

• Corticoids like prednisone or prednisolone at 1mg/kg/d PO during 2 months do not interfere with the test. If more dosage has been given or during more time, we recommend removing the corticoid for 3-4 weeks and then take the sample.
• If a depot formulation has been given, it should pass 4 weeks before taking the sample.
• Topical or otic formulations: do not interfere.

Cyclosporine: it does not interfere with the test if given at 5mg/kg/d during 2 months. If more dosage has been given or during more time, we recommend removing it for 1 month.

Antihistaminic and Essential fatty acids: do not interfere.

Oclacitinib (Apoquel): does not interfere with the test.
