Specific IgE C82 — Lidocaine
The study of specific immunoglobulin E class antibodies to lidocaine is conducted to assess the body's allergic sensitization to a local anesthetic. The test is used as part of comprehensive allergological diagnostics, when allergic reactions to medications are suspected, and for monitoring allergy development risk when using lidocaine.
Test composition:
- Determination of specific IgE class immunoglobulins in blood serum
- IgE antibodies to lidocaine are tested
- The test aims to detect sensitization fact and degree of the body's allergic response to lidocaine
- The study is performed by enzyme immunoassay or immunochemiluminescence method, with high sensitivity and specificity
- The result reflects specific IgE concentration and is used for immunological assessment of the body's reaction to lidocaine
Clinical significance:
- Determination of specific IgE allows assessment of the allergic reaction character on contact with lidocaine
- The test is used for monitoring patients with chronic allergic diseases and suspected drug allergy
- Results are used for assessing risk of allergy development to lidocaine and planning safe medication use
- The study complements clinical data and other laboratory test results
Biomaterial: Venous blood
- Blood is submitted fasting
- It is recommended to avoid alcohol the day before the test
- Before blood collection, it is advisable to avoid intense physical exertion and stressful situations
- The attending physician should be informed about taking hormonal medications, immunomodulators, and antihistamines.
- Suspected allergic reactions to local anesthetics
- History of intolerance or allergy to lidocaine
- Need for risk assessment before procedures using lidocaine
- Prolonged or repeated contact with the medication
An elevated specific IgE level indicates the presence of allergic sensitization to lidocaine
A low level may indicate absence of significant sensitization or formation of immunological tolerance
Final interpretation is performed by a physician considering the clinical picture and other test data
Which doctor to consult:
Allergist — for diagnosing drug allergy, identifying causes of sensitization, and selecting individual treatment tactics
Immunologist — for assessing immune system status and analyzing immune response features to drug allergens
General practitioner — for initial assessment of the patient's condition, prescribing examinations, and referral to specialists
