What is the ideal condition for performing patch tests?
- When patients have a history of allergic reactions
- When patients are taking high doses of systemic drugs
- When patients are not influenced by immunosuppressive medications (correct)
- When patients are experiencing active symptoms
What may happen if patch testing is performed while a patient is on systemic immunosuppressive medications?
What may happen if patch testing is performed while a patient is on systemic immunosuppressive medications?
- It can lead to false-negative results (correct)
- It will not affect the test results
- It increases the likelihood of positive patch test responses
- It will enhance the test's accuracy
If stopping immunosuppressive drugs is not feasible for a patient, what is the recommended alternative?
If stopping immunosuppressive drugs is not feasible for a patient, what is the recommended alternative?

- Switch to a different type of patch test
- Increase the dosage of immunosuppressive drugs
- Reduce the dose of the immunosuppressive medication (correct)

Study Notes
Patch Testing and Immunosuppressants
- Systemic drugs suppressing T-cell responses also suppress patch test reactions.
- Ideal patch testing involves patients not taking immunosuppressant medications (e.g., prednisone, cyclosporine).
- If stopping immunosuppressants is not possible, reduce the dose to a minimum to prevent false-negative patch test results.
