The drug solution is injected into the epidermis and dermis for allergy testing. The injection site is typically chosen on the neck or tail area, depending on the animal being tested. When preparing for the injection, use your left hand to gently lift and stretch the skin, creating a taut surface. With your right hand, hold the syringe at a 30-degree angle relative to the skin surface. Carefully insert the needle through the skin, ensuring it enters just beneath the epidermis. Once in place, slowly inject the solution. A small, raised bump—resembling a papule—should appear at the injection site, indicating proper placement.
After removing the needle, do not apply any disinfectant or pressure to the area. A correct injection feels slightly more resistant due to the tightness of the skin layers, which is a sign that the technique was performed properly. If the injection feels too easy or smooth, it may indicate that the needle has entered too deeply, possibly beneath the skin. In such cases, it’s necessary to withdraw the needle and re-puncture at a different spot to ensure accurate delivery of the test substance.
This method requires careful handling and attention to detail, as improper technique can lead to inaccurate results or unnecessary discomfort for the subject. Always ensure the syringe is properly filled and the needle is sharp to minimize pain and improve accuracy. It's also important to maintain a clean environment to reduce the risk of infection. After completing the injection, observe the site for any immediate reactions, as this can help in interpreting the allergy test results more effectively.
