Q: Why consider serological allergy testing?
A: To give the option of providing the only management solution that can modify the natural course of a pre-existing hypersensitivity and result in the establishment of long-term clinical tolerance (1,2).
Q: Why choose serological testing over intradermal testing (IDT)?
A: Here are the top 5 reasons:
1. Minimal preparation / less invasive for patient.
2. Time efficient – quick and easy sample submission process.
3. Can be carried out while skin lesions are present.
4. Flexible – samples can be taken and stored when the patient is most symptomatic / off medication and then tested when required.
5. No difference in response rate to immunotherapy when compared to using intradermal testing (3,4).
