Our available tests

Allergies come in many forms and can trigger multiple conditions. Along with a careful clinical history, we test for the allergens that are most relevant to you, to ensure the most effective treatment.
The skin prick test is a routine test performed by allergists. It involves placing small amounts of allergens onto the skin then with a small lancet a superficial break in the skin is made. The test is monitored for 15 minutes and observed for any signs of a wheal or flare reaction. The skin prick test is low risk and delivers quick results for the doctor to gain an indication of each patient’s sensitivity. After an initial consultation, Dr Baker determines which allergens to test. The test will span over 40 allergens on your first appointment, with foods and inhalants extensively tested at no extra cost.
Dr Baker’s preferred method of treatment is immunotherapy with a sublingual vaccine that is made on the premises and prescribed specifically for each patient. The treatment costs less than $1 a day and targets the allergens causing the patients sensitivity through a desensitising process.In order for the vaccine to be prescribed Dr Baker performs a second set of tests involving intradermal testing using very weak dilutions of the specific allergen in order in order to determine a safe and effective starting dose for each patient. The test involves injecting small amounts of diluted allergen extracts just under the skin. After waiting ten minutes, the skin is examined for a reaction. This procedure can be repeated using two to three dilutions of the same extracts, getting subsequently stronger or weaker each time. Once the patients skin reacts positively to a particular allergen(s), the test is complete and a vaccine can be made to desensitise against the allergens causing the patient problems.
Dr Baker has an accreditted NATA laboratory on the premises where he performs the IgE tests. The levels of IgE immunoglobulin are often elevated in patients suffering from allergy. It is a quantative test that gives the doctor a clearer indication that the patient’s problem is allergy and not something else. The specific IgE sometimes referred to as RAST is a qualative test that measures the levels of IgE immunogloblin against specific allergens including both foods and inhalants.
This test is performed in cases of contact dermatitis (Eczema) or any other allergy is suspected. The allergens are prepared in appropriate concentrations in white soft paraffin (e.g. Vaseline) and are then spread on to discs, 1 cm diameter. The discs (which are made of a special metal, cannot themselves provoke a reaction) are placed on the skin, usually on the back, and are kept in place by hypoallergenic tape. The skin is coded appropriately and the patient is asked to keep the skin dry. The patches are left in place for 48 hours. After 48 hours the discs are removed, the skin is examined and any redness or swellings are noted. The skin is re-examined after a further 48 hours for any remaining local redness or swelling. The interpretation of this form of testing is not as simple as it sounds and tends to be carried out by a doctor. The symptoms of contact dermatitis need to be brought under control before patch testing can be carried out, otherwise the results will be unreliable. Steroid creams need to be stopped for 3-4 weeks before testing as they may suppress the test response. Any professional interpreting skin, blood or patch tests must first interpret the results in the light of the patient’s history. No test should be read in isolation.
Despite continuing advances in the diagnosis of immunoglobulin E (IgE) mediated inhalant and food allergy utilizing in vitro technology, the otolaryngic allergist should be familiar with the principles and practise of skin endpoint titration (SET). Skin testing techniques and responses will allow proper interpretation of in vitro-based antigen vial tests, will permit the blending of in vitro and in vivo test methods within the allergy practice, and will often give a clearer picture when a practitioner is caught in a confusing situation. Preparing to do a skin Endpoint Titration Test is time consuming and labour intensive requiring a trained scientific officer or doctor to perform the tests. A immunotherapy dosage for either injection or sub-lingual vaccine can be better determined using this method.

Extract Taken from

A RAST test measures the level of allergen-specific IgE in your blood. That is, it measures the concentration of antibodies your body has created to against a particular food allergen. Interpreting a RAST result is slightly more complicated, however. This is because not everyone with the same concentration of allergen-specific IgE in their blood will react in the same way to the presence of an allergen in vivo (that is, in the flesh).

Someone with a relatively low concentration of allergen-specific IgE may have a fairly severe reaction while someone with a higher concentration of allergen-specific IgE may not react at all — that is, they’re not truly allergic to a food even though the blood test comes out positive. (This is known as a false positive.) RAST tests have a high sensitivity and fairly low specificity, meaning that they have a low rate of false positives and a fair number of false negatives, though this varies by allergen. In general, lower rates of allergen-specific IgE are correlated with a lower chance of reacting in a double-blind food challenge or in a real-world setting, especially if skin test results are negative and if there’s been no history of reaction to a given food.

Different foods have different specific IgE levels that are considered “predictive.” Where most people with a given level of specific IgE may react to one particular food, most people with that same level of specific IgE may not react to another food. Researchers determine these threshold levels by comparing RAST test results to the results of double-blind food challenges in order to find a level of specific IgE on the blood test where a very high percentage of people are truly allergic. This means that someone whose test results “look” identical for two different foods may be considered to have a positive result for one and a negative result for the other, if the foods have different threshold levels.

Specific IgE tests are usually returned in units of micrograms per milliliter (μg/mL). Some, however, are returned on a numerical rating scale (often, but not always, from 0 to 5 or 6). On rated tests, 0 almost always indicates an exceedingly low chance of a true food allergy, while the higher numbers normally mean very strong probability of allergy and a strong likelihood of a severe reaction. Your allergist may use these results to help determine some aspects of your treatment — to see whether a child is showing signs of outgrowing a food allergy, for instance.

Patient Guide for Allergy Assessment

Booking and Preparation

Avoid fragrances, stop certain medications as directed before your appointment to ensure accurate testing, and please inform the nursing staff if you are taking beta-blockers or tricyclic antidepressants. Also, refrain from using specific nasal sprays a week before testing.

Day of Consultation

On allergy testing day, the doctor will assess your history and choose allergens to test. The nurse, supervised by the doctor, will conduct the tests. Based on the initial results, further testing may be done the next day to gauge your sensitivity, depending on your chosen treatment with the doctor.


After your initial consultation, you'll undergo testing for inhalant and food allergies that the doctor suspects could be the cause of your allergy. We use both forearms to test for multiple allergens, aiming to obtain a comprehensive understanding of your allergic condition.


We provide immunotherapy and educate our patients on allergy-free living. We offer two types of immunotherapy: custom sublingual vaccines tailored to your sensitivity and injections administered under doctor supervision to gradually desensitize you to allergens. Unlike costly over-the-counter options, our sublingual vaccines are tailored and effective.

Follow Up

We'll schedule a follow-up appointment six months after starting treatment to assess your progress. Regular testing every six months will help strengthen your immunotherapy until your allergic symptoms improve.

Got any questions?

Allergy testing identifies allergens that cause allergies. If allergies are not treated they can often get worse and weaken your immune system and set you up for dangerous complications such as bacterial or fungal infections in the sinuses, lungs, ears or skin. Testing for allergies is particularly important in children to ensure that more chronic conditions do not develop from untreated allergies.

Most allergic tests involve minimal discomfort. Skin prick tests may cause slight itching or a pricking sensation, but it’s generally tolerable.

  • Skin Prick Test
  • Patch Test
  • Serial Titration Test
  • IgE and Specific IgE (RAST) test

Most of your results will be determined on the day of your test. If not the first day by the second appointment. If Dr Baker prescribes a blood test this can take longer.

There can often be delayed reactions which are relevant. These are monitered by our team.

  • We ask you to refrain from wearing scented body lotion, perfume, hair spray as many of our patients may be sensitive to fragrances.
  • There is no need for fasting prior to your appointment however, if you are taking anti-histamine or anti depressant medication it is important to stop these prior to testing either 5 to 7 days prior to your testing. Some of these anti-histamines not to be taken 7 days prior to testing are: Claritin, Clarinex, Zyrtec, Xyzal Allegra. Over the counter antihistamines Benadryl cold and sinus medications, sleep aids such as Tylenol PM.
  • Do not take Tagamet, Pepcid, or Zantac 1 day prior to testing.
  • Do not take tricyclic antidepressant medication. Please inform our nurse if you do. These medications must be stopped 7 days prior to testing with the permission of your precribing doctor.
  • Do not take beta-blocker medication. Please inform the nursing staff if you do. Beta blockers are medications used for the treatment of high blood pressure, migraine, heart problems, performance anxiety or glaucoma (ey drops) with the permission of your prescribing doctor. Do not use nasal antihistamine sprays such as Azelastine or Olopatadine at least 1 week before testing.

We are a Medicare Accredited Medical Practice.

Immunotherapy by injection is covered by medicare. Some private insurance companies cover the sublingual vaccine costs.

  • Antihistamines: It’s preferable not to take antihistamines or nasal sprays containing antihistamines prior to testing. However, patients should call to discuss with the clinic if they are, for some reason, unable to stop the medication.
  • Antidepressants: Antidepressants can also affect testing. Please inform the doctor if you are taking any antidepressants.
  • Antimigraine: Antimigraine products can also affect the testing. Please inform the doctor if you are taking any antimigraine products.
