ALLERGY, ONION (PYAAZ)

The Onion Allergy Test (Pyaaz) is a specialized blood test that measures specific Immunoglobulin E (IgE) antibodies against onion proteins. Onion allergy is a food allergy that occurs when the immune system mistakenly identifies onion proteins as harmful and triggers an allergic response. Symptoms may vary from mild skin irritation and digestive discomfort to respiratory symptoms and, in rare cases, severe allergic reactions.

This test helps identify whether onions are responsible for allergic symptoms and assists healthcare providers in developing appropriate dietary and treatment plans.

Benefits of the Test

• Accurately detects allergy to onions.
• Helps identify food allergens causing allergic symptoms.
• Supports personalized dietary recommendations.
• Assists in preventing recurrent allergic reactions.
• Useful for investigating unexplained food-related symptoms.
• Helps distinguish food allergy from food intolerance.

Why Doctors Recommend This Test

Doctors may recommend the Onion Allergy Test for individuals experiencing symptoms after consuming onions or onion-containing foods. Common symptoms include:

• Skin rash, hives, or itching
• Swelling of the lips, tongue, or throat
• Abdominal pain and bloating
• Nausea, vomiting, or diarrhea
• Sneezing or nasal congestion
• Coughing, wheezing, or breathing difficulties
• Recurrent allergic reactions without a clear cause

This test helps allergists and physicians accurately identify onion allergy and guide proper treatment and dietary modifications.

• No fasting is required.
• Continue regular medications unless advised otherwise by your doctor.
• Inform your healthcare provider about any allergy medications and previous allergic reactions.
• A blood sample is collected for analysis.

Patient-Friendly Summary

The Onion Allergy Test (Pyaaz) is a blood test used to determine whether your immune system reacts abnormally to proteins found in onions. Onion allergy can cause symptoms such as itching, skin rash, stomach discomfort, swelling, nasal congestion, and breathing problems. Since these symptoms may resemble other food allergies or digestive conditions, identifying the exact cause is important. This test provides reliable information about onion sensitivity and helps doctors recommend appropriate dietary changes and treatment. It is a safe and convenient blood test that requires no fasting. Early diagnosis can help prevent repeated allergic episodes and improve overall quality of life.
