Allergy Testing In Singapore (For Adults & Kids)
If you have ever suffered from an allergy attack, then you know pretty well that there is more to allergy symptoms than just nasal discomfort. They can have a huge impact on your quality of life, perhaps making it difficult to go about your daily activities.
Allergy testing is usually performed to help identify specific allergens. If you are suffering from allergies or you think you might be having an allergy, it is imperative that you know exactly what might be triggering your allergy problems. And allergy testing is a way for you to figure out what allergens are causing your allergic reactions.
However, this does not entirely imply that allergy testing is a straightforward procedure! And a lasting solution to your problems can only be reached by working with your doctor who can conduct the appropriate allergy testing that will detect the primary cause of your discomfort.
It is also worth noting that when it comes to allergy testing, one size doesn’t always fit all. And this simply implies that your doctor will have to closely work with you to establish the test that is best suited to your needs.

What types of allergy testing procedures are available in Singapore?
The two main allergy testing techniques available in Singapore include the skin prick test and the blood test. Based on the type of information available, your doctor will choose the best test that is suitable for your case.
During your appointment with your doctor, you’ll be asked a couple of questions to help create a case file. Prior to your visitation, you are highly advised to keep a diary of your symptoms that you suspect are behind your allergy woes. Of course, your doctor will also ask questions regarding your family history, lifestyle as well as any other relevant questions that may be associated with your allergy symptoms.
This information is vital because it allows your doctor to determine the best allergy testing method that is suited to your symptoms and needs. Also, before the test, your doctor will discuss with you all the potential advantages and disadvantages of each test, just to ensure you select the best test that is suited to your needs and preferences.
What does the allergy blood test entail?
RAST blood allergy testing is a method used to identify IgE antibodies that are produced toward specific allergens. Currently, there are numerous allergen panels that are testable through IgE antibodies blood test.
This is usually a simple and straightforward procedure that only involves the drawing of blood from the patient. Generally, you’ll have your blood test results after five or seven working days.
What is a skin prick test?
Just as mentioned earlier, this refers to a diagnostic procedure that enables your doctorto precisely identify your trigger allergens. This involves using commercial-grade and standardized allergen extracts of a wide range of species-specific allergens such as mold, pet dander, pollen, foods as well as dust mites.
The skin prick test is not only simple and straightforward, but highly effective as well. On most occasions, it is performed over the arm of the patient. It evaluates immediate allergic reactions to as many as more than forty different substances in a single test. In patients, this test is often performed on the forearm or in some cases, the test can be conducted on the back of the patient!
How is the skin prick test conducted?
During this particular procedure, the patient’s forearm is first sterilized using alcohol. After that, the targeted area is marked out to help locate the various zones for testing each allergen. A few drops of allergen are administered into the skin via a small puncture using a skin applicator. And after nearly twenty minutes, you’ll receive your results.
Regarding the associated side effects, patients usually experience mild itchiness and redness in the tested body part. But most importantly, these symptoms usually disappear after a few minutes. The doctor will then inspect the tested area for any visible signs of bumpy swelling and redness, and review the extent of swelling. And if you experience any reaction toward a particular allergen, you’ll potentially experience swollen hives referred to as wheals at the sections where the culprit allergens were introduced.
What should you do before going for a skin prick test?
- It is important to note that certain medications, including cough syrup, antidepressants as well as steroid-based drugs can potentially impact the reaction toward allergens in this type of allergy test.
- If you are suffering any underlying skin conditions in the tested area, it will be pretty hard to precisely interpret your results.
- Patients should stop using either topical or oral antihistamines at least seven days before going for the skin prick test.
How soon will I have my allergy test results back?
As you may have realized, the skin prick test is a somewhat simple and straightforward procedure that only takes nearly twenty minutes for your results to be out. On the other hand, you will have to wait or between one and two weeks for your results to be ready if you opt for the allergy blood test.
How reliable and accurate are allergy tests?
The skin prick test is relatively more effective and reliable. Of course, it needs to be performed in the best way possible and with your doctorfor it to yield great results. Regardless, it is worth mentioning that there is a slight possibility of patients having a negative skin prick test but still, suffer an allergy problem at a certain point in time during their lifetime. In medical terms, this phenomenon is known as a false negative and can occur as a result of a number of factors, including:
- Your system or body may have had a serious allergic reaction
- You may have used certain medications that may have impacted the results of your test, resulting in a false-negative result.
- Technique variability: Just like any other medical procedure, this particular test might be conducted differently in terms of techniques and skills.
It is important to mention that the allergy blood test boasts an edge over its skin prick test counterpart in one particular area. To be more specific, the results of the allergy blood tests are not entirely affected by the type of medicines you are currently using. Nonetheless, there is always a slight chance of a false positive, and this usually causes unnecessary confusion as well as anxiety in allergy sufferers.

Allergy Testing FAQs
This is one of the two proven tests for allergies. To be more precise, RAST is an acronym for a radio-allergo-sorbent test.
During this particular procedure, your doctor will draw some blood samples from your body which will thereafter be tested for specific antibodies to help identify your possible allergens.
Allergy blood test boasts a number of advantages, such as:
- It safe for children as well.
- Patients who are currently using other medications can also have this particular test conducted on them because the results won’t be affected by those medications.
- If you are currently suffering from any underlying skin condition, this particular test won’t exacerbate your symptoms.
- Your risk of experiencing an allergic reaction is almost zero!
As earlier explained, a blood allergy test is a relatively more complex procedure. On average, you’ll have your test results after five or seven days. Of course, if you are someone in a hurry, this may not be the best allergy test for you.
Just as the name suggests, this is a simple procedure that involves your doctor pricking the outermost layer of your skin and administering various allergens such as dust mites, pet dander, pollen, food, and fungi into your skin. It is important to note that doctors only administer standardized, industrial-grade allergens that are safe and won’t adversely affect you.
Your doctor will apply a small amount of allergen beneath your skin’s outermost layer using a miniature lancet that is minimally invasive. Other names used to describe this type of allergy test include the puncture test or the skin scratch.
Because this test involves the use of unique microneedles that don’t penetrate your skin’s surface, it is not painful in any way. As explained earlier, your doctor will only insert a small number of allergens into your skin using very small lancets. The area tested is usually marked before being administered with a few drops of allergens. If anything, patients usually experience mild discomforts that last a few seconds or minutes.
Generally, this type of allergy testing is not only safe, but simple and fairly easy to conduct as well. as such, it usually won’t lead to any life-threatening side effects. What’s more, it is usually carried out in a safe environment where the doctor is there to offers close supervision.
However, some patients also experience some sort of itching or redness, specifically on the rea where the test is conducted. Incidences of patients experiencing a severe allergic reaction to skin prick tests are usually rare. This type of allergy test is not suited for:
- Patients suffering from an extreme inflammatory condition that impacts a large area of their skin such as eczema.
- Patients currently using antihistamine medications and are not in a position to quit before having a skin prick test.
- Any individual having a history of a severe allergic reaction (anaphylaxis) toward particular allergens.
Skin prick test is somewhat more affordable and also you can have your results on the same day.
It is worth noting that there is always a slight possibility that you may experience a severe reaction toward one of the allergens administered into your body during the test. Also, patients may be needed to stop using the drugs that they may be taking currently.
While the testing techniques discussed above are the most commonly used, there is also a third test known as a skin patch. It can be used to detect contact allergies caused by particles in a patient’s drugs, topical creams, cosmetics, and even fragrances. Of course, when you visit your doctor, they will discuss with you in detail all you need to know about the skin patch test.
Of course, this varies from one person to the other, depending on an individual’s exposure to new allergens and perhaps the onset of new allergy symptoms.
Clinical research has shown that there are certain drugs (cetirizine, antihistamines such as loratadine, and piriton) that tend to impact the results of the skin prick test. This now implies that before you go for the skin prick test, you’ll be required to tell your allergist all the medication you are currently taking.
Of course, you will need to talk to your insurance provider to verify whether it covers your test or not.
Are allergies curable?
Arguably, the best way to protect yourself against allergies is to know and avoid all the potential allergens that might be responsible for your symptoms. Unfortunately, it is not always possible to avoid coming into contact with allergens! This simply implies that visiting your local Singapore doctor is perhaps your first line of defense against allergy problems.
Thanks to the advancements in the medical industry, we now have a variety of drugs that can help you manage your symptoms. They include corticosteroids, antihistamines as well as decongestions. Also, there is allergen immunotherapy, a lasting type of treatment that is employed to alleviate different types of allergy symptoms. In case you didn’t know, this is a relatively effective and safer type of allergy treatment technique that targets a specific allergen and subsequently modifies the immune system of the patient to adapt and somehow desensitize the patient’s body against the detected allergen.
