What is general anaesthesia allergy testing?
General anaesthesia allergy testing is a specialist diagnostic service used when an allergic reaction has occurred, or is suspected to have occurred, during or shortly after the administration of anaesthetic drugs. These reactions may range from mild symptoms to severe, life-threatening responses such as anaphylaxis.
The aim of testing usually is to identify the specific item/drug responsible for the reaction, so that future procedures can be planned safely using appropriate alternatives.

Our adult allergy specialist
Dr Gururaj Arumugakani is a Consultant Allergist and Immunologist with decades of experience, currently practicing at UCLH. He is an expert in general anaesthesia allergy testing and performs the testing with a high level of skill & care. ​
​
What Does the Testing Involve?
​
-
Skin prick testing
-
Intradermal testing
A comprehensive panel of relevant anaesthetic drugs is tested, tailored to the medications used during the original procedure and current clinical guidelines.​​
​
Why is Testing Important?
General anaesthesia allergy testing helps to:
-
Identify the causative drug
-
Exclude drugs that are safe to use
-
Guide anaesthetists on safe alternatives for future procedures
-
Reduce anxiety for patients requiring further surgery
Specialist allergy testing allows surgical procedures to go ahead in the safest possible way.
​
Testing can take place 4 weeks or more after the reaction occurred.
What to expect
Testing typically takes approximately half a day. This allows sufficient time for:
-
Skin prick testing
-
Intradermal testing
-
Observation following testing
-
Discussion of results and next steps
Following completion of testing:
-
A detailed report is provided
-
Clear guidance is given regarding which anaesthetic drugs should be avoided
-
Recommendations are made for safe alternatives for future procedures
-
Information can be shared with your surgical and anaesthetic teams (with your consent)
