Determine your allergen
According to the American College of Allergy, Asthma and Immunology, allergies affect more than 50 million people per year. Allergy testing is a valuable tool used to identify specific allergens that may be causing allergic reactions in an individual. Whether you experience symptoms like itching, sneezing, rashes, or gastrointestinal issues, allergy testing can provide valuable information that guides treatment and lifestyle adjustments.
An allergy is an overreaction of the immune system to a substance that is usually harmless to most people. These substances, known as allergens, can include pollen, pet dander, certain foods, insect stings, and medications. When a person with an allergy is exposed to an allergen, their immune system mistakenly identifies it as a threat and mounts a defensive response, leading to various symptoms. The immune system overreacts to the allergen by producing Immunoglobulin E (IgE) antibodies, which release histamine and other chemical mediators, causing an allergic reaction.
Diagnosing an allergy involves a combination of a detailed medical history, physical examination, and specific diagnostic tests (skin prick tests, patch test and blood tests). The goal is to identify the substance (allergen) responsible for causing allergic reactions and to determine the severity of the allergy. Early diagnosis can help inform lifestyle, environmental changes and improve quality of your life.
Allergy symptoms can range from mild to life-threatening. While some people may only experience mild discomfort, others may suffer from severe and potentially dangerous reactions. It is important to recognize the signs of an allergic reaction and seek appropriate medical care, especially if symptoms are severe or involve difficulty breathing, swelling, or anaphylaxis.
An allergen panel screens for multiple allergen and is more cost-effective as it helps to identify the specific allergen, eliminating costly single allergen testing. Testing for a panel of allergens, rather than just a specific allergen, is often recommended because it provides a more comprehensive understanding of what might be triggering allergic reactions. Whether you’re dealing with respiratory, skin, food, or other types of allergies, a comprehensive panel test can significantly improve your ability to manage your condition and prevent future allergic reactions.
Allergy blood tests offer a safe, convenient, and comprehensive way to diagnose allergies, particularly in cases where skin testing is not feasible or poses risks. They provide quantitative results that can be used for long-term monitoring and are especially useful for individuals with severe allergies, skin conditions, or those taking medications that interfere with skin tests.
| Test | Price (SGD) |
|---|---|
| Single Allergen Screening | From 60 |
| Food Allergy Screening (8 allergens) | 400 |
| Inhalation Allergy Screening (15 allergens) | 600 |
| Comprehensive Allergy Screening (59 allergens) | 650 |
The food allergy screening panel consists of:

An allergy blood test is a diagnostic tool used to detect the presence of specific IgE antibodies in the blood. These antibodies are produced by the immune system in response to allergens, which are substances that can trigger allergic reactions. The test helps identify which substances a person is allergic to.
During an allergy blood test, a small sample of blood is drawn from a vein in the arm. This sample is then analyzed in a laboratory to measure the levels of IgE antibodies associated with specific allergens, such as pollen, pet dander, foods, or dust mites. The results indicate whether you have an allergy and the severity of your sensitivity to each allergen tested.
An allergy blood test is recommended in the following situations:
Allergy blood tests are generally very safe. The risks are minimal and include mild discomfort at the blood draw site, such as slight pain, bruising, or, in rare cases, fainting. There is no risk of an allergic reaction since the test does not involve exposure to allergens.
Allergy blood tests are generally accurate, especially for identifying common allergens. However, the sensitivity and specificity can vary depending on the allergen. Blood tests are particularly useful for detecting allergies when skin testing is not possible or practical. Your healthcare provider will interpret the results in the context of your symptoms and medical history.
Allergy blood tests are effective at detecting IgE-mediated allergies, which are the most common type. However, they may not identify non-IgE-mediated allergies or intolerances, such as lactose intolerance or celiac disease. For these conditions, other types of tests or evaluations may be needed.
No special preparation is required for an allergy blood test. You can continue taking your medications and eat and drink normally unless your healthcare provider gives you specific instructions to the contrary. If you have any concerns or questions, it’s best to discuss them with your healthcare provider before the test.
Allergy testing is a vital component of allergy diagnosis and management, offering critical insights into the specific allergens affecting patients. Comprehensive testing not only enhances patient safety and comfort but also contributes to more effective and personalized management strategies, ultimately improving patient outcomes and quality of life.

Allergy testing is essential for diagnosing allergies and understanding the specific triggers that contribute to a patient's symptoms. Allergies can significantly impact quality of life, leading to chronic discomfort, impaired functioning, and, in severe cases, life-threatening reactions. By identifying the precise allergens responsible for these reactions, we can develop targeted management strategies to alleviate symptoms, prevent exposure, and enhance overall well-being.
