What is this test?
The Chicken Serum Protein IgE test is a blood test that detects specific IgE antibodies in your blood that react to proteins found in chicken serum. This test uses a method called RAST (Radioallergosorbent Test), which is a laboratory technique designed to identify whether a person has an allergic response to particular substances. A healthcare provider will draw a blood sample from your arm and send it to a laboratory for analysis.
How should I prepare for the test?
Generally, no special preparation is needed for this blood test. You can eat and drink normally before the test. However, it is important to inform your doctor about any medications you are taking, as certain drugs may affect test results. Also, let your healthcare provider know if you have had any recent allergic reactions or have been exposed to chickens or chicken products.
What happens during the test?
During the test, a healthcare professional will clean the skin on your arm with an antiseptic wipe and place a small needle into a vein to draw blood. You may feel a brief sting or pinch. The blood sample will be collected in a tube and sent to a laboratory. The test typically takes only a few minutes, and you can resume your normal activities immediately afterward.
Reference range
Class 0: Negative (<0.35 kU/L); Class 1: Low positive (0.35-0.70 kU/L); Class 2: Moderate positive (0.70-3.50 kU/L); Class 3: High positive (3.50-17.50 kU/L); Class 4: Very high positive (17.50-50.00 kU/L); Class 5: Very high positive (50.00-100.00 kU/L); Class 6: Extremely high positive (>100.00 kU/L)N/A
No special preparation required. Patient may continue regular diet and medications unless otherwise instructed by physician. Avoid antihistamines and immunosuppressive medications prior to testing as per physician order.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
This test helps diagnose whether you have an allergy to chicken serum proteins. A positive result indicates that your immune system produces IgE antibodies specific to chicken proteins, which means you may have or be at risk for an allergic reaction when exposed to chicken. This information is valuable for proper diagnosis, avoiding trigger foods, and developing an appropriate treatment plan including potential immunotherapy or emergency action plans for severe reactions.
