What is the safest way to perform skin prick testing during an allergy test?

Multi-needle medical devices (e.g., spider-like plastic frames with eight small needles attached) are a safe, effective and efficient way to deliver testing. If single needles are used, a new, sterile needle is required for every skin prick or scratch. Discard any needle(s) after contact with a patient. Medical devices used for skin prick testing must have validated instructions for use and a medical device licence from Health Canada.
