Lidocaine

Lidocaine is a commonly used local anesthetic for temporary numbing of an area before medical or dental procedures. The Lidocaine (C82) laboratory test detects specific antibodies in the blood to identify potential allergies or hypersensitivity reactions to this substance.

Role

• Identify patients at risk of allergic reactions to lidocaine.
• Prevent severe complications during procedures requiring local anesthesia.
• Monitor immune response to lidocaine.

Advantages

• Safe and rapid method for allergy screening.
• Helps prevent severe reactions during treatment.
• Can be performed prior to any procedure involving lidocaine use.

Indications

• History of allergic reactions to local anesthetics.
• Patients receiving lidocaine for the first time with increased risk.
• Unexplained reactions after previous lidocaine administration.

Contraindications

• No absolute contraindications, but results should be interpreted by a medical specialist.

Procedure

1. A venous blood sample is collected.
2. The sample is analyzed for lidocaine-specific IgE antibodies.
3. Results are interpreted by a physician.

Results

• Positive result: Presence of lidocaine-specific IgE antibodies, indicating a possible allergy. Severe reactions should be avoided.

• Negative result: No specific antibodies detected, suggesting a low risk of allergic reaction.
