kUA/L

This test measures the concentration of allergen-specific Immunoglobulin E (IgE) antibodies in the blood directed against Lidocaine, a local anesthetic. In the context of a drug allergy profile, it helps identify Type I hypersensitivity reactions. While lidocaine allergies are rare (often being reactions to preservatives or epinephrine), a positive result suggests a risk of immediate hypersensitivity, including urticaria, angioedema, or anaphylaxis.

Why Context Matters

True IgE-mediated allergy to amide-type anesthetics like Lidocaine is clinically rare. A second opinion is vital to differentiate between IgE-mediated allergy, toxicity from accidental intravascular injection, vasovagal responses, or reactions to preservatives like methylparaben or sulfites.

Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
