Review evaluates in vivo and in vitro methods for detecting allergen-specific IgE in humans and animal models, highlighting technical limits that keep in vivo testing as the diagnostic standard.

Key Points

To evaluate historical and current in vivo and in vitro diagnostic methods used to detect allergen-specific IgE antibodies across human and animal models.
Reviewed conventional in vivo diagnostic techniques, specifically human skin prick testing and animal passive cutaneous anaphylaxis assays.
Assessed standard in vitro assays, including enzyme-linked immunosorbent assays, radioallergosorbent tests, and advanced protein microarray platforms.
Analyzed mechanistic assay challenges, focusing on competitive binding interference between serum IgG and IgE antibodies.
In vivo assays remain the diagnostic gold standard by delivering a functional readout of IgE activity, despite requiring higher technical expertise and greater costs.
In vitro assay sensitivity is substantially limited because allergen-specific serum IgG concentrations exceed IgE by several orders of magnitude, causing direct competition for allergen capture sites.
High-density protein microarrays provide concentrated allergen targets in small reaction volumes, offering a potential path for in vitro assays to supplement or eventually replace in vivo diagnostics.
