The usefulness of plasma histamine and different tryptase cut‐off points in the diagnosis of peranaesthetic hypersensitivity reactions
Anaesthetic hypersensitivity reactions can be IgE‐ or not IgE‐mediated and are a challenge to find the causal agent. Histamine and tryptase determination are classically considered useful in the diagnosis of these reactions. The aim of our study was to assess the diagnostic usefulness of plasma histamine and different cut‐off points of serum tryptase.
