Improvements in skin-testing technique
Abstract:Allergy skin testing is the primary modality used in the diagnosis of allergic diseases and guides development of treatment and avoidance plans. The goal of the Allergist is to skin test the appropriate population with a device and technique that minimizes pain while maximizing sensitivity and specificity. The debate involving the use of intradermal versus skin-prick testing in the diagnosis of aeroallergy has been long lasting. Past and present medical literature will be reviewed, establishing the lack of diagnostic use of intradermal testing in the setting of aeroallergy. New skin devices continue to be developed with a trend toward production of multidevices. Performance characteristics of various skin test devices will be reviewed with an emphasis on sensitivity, specificity, and variability of skin-prick testing devices. Significant statistical differences exist between all devices tested and reported in the literature. Whether these statistical differences equate to clinical differences is not known. With this review the practicing allergist should carefully evaluate multiple different devices and choose a device that suits their practice needs. In addition, allergists must ensure that technicians are sufficiently trained on the correct use of their device and should conduct continuing education to ensure that proper skin testing techniques are being used in their practice. Finally, the use of skin testing in pediatrics will be reviewed with a focus on safety. Care should be taken when skin testing infants ≤6 months of age, especially in the setting of eczema and a family history of atopy.
