At Sullivan Nicolaides Pathology (SNP) we perform tests that help your doctor diagnose the cause of your allergy.

Your test may involve having a blood sample collected at one of our collection centres and tested in our laboratory using RAST® or ImmunoCAP ISAC®. Or your doctor may ask you to have a skin prick test, performed under medical supervision at one of our highly specialised procedural centres.

Determining allergies is complex, and often a diagnosis must be made by correlating test results with your symptoms and clinical history.

Your Pathologist -
Dr Daman Langguth FRACP, FRCPA
At SNP your test is in the skilled and experienced hands of an expert team lead by Dr Daman Langguth.

As a clinical pathologist Dr Langguth is a medical doctor who has undergone many years of additional specialist training in rheumatology and immunology in Perth and Brisbane. With expertise in the investigation of auto-immune disease, allergy, and immune deficiency, he is often called on for expert opinion by local and international colleagues.

Dr Langguth is committed to allergy research and is at present working on a project investigating Australian grass pollens, and in particular the role of paspalum (Bahia grass) in allergic rhinitis. He is also committed to maintaining and improving professional standards and guidelines in immunopathology and general pathology through membership of a number of state and national committees.

What tests are available?

Skin prick tests are a simple, reliable way to test for many allergens. Usually, they are performed on the inside of
your forearm. A device is used that pricks the skin and introduces tiny amounts of individual allergens.

The device has 8 different allergens so your test may include groups of foods such as cow's milk, peanut, prawn,
wheat and yeast; moulds; pollens and general stimuli such as cat and dog dander and hair, house dust mite and mixed feathers. The selection of allergens tested will depend on your age.

If you test positive, a small lump will develop at the site and there may be some redness and itching. The whole procedure will take about 30 minutes. If you have a positive test result, it is likely to be associated with an allergy, but your doctor will need to consider it in the context of your clinical history.

Positive results may occur in people with no history of allergies. If the results are negative, there is a strong chance you do not have an allergy to those substances.

Skin prick tests are extremely safe but, because there is a small risk of a strong reaction, you will need to have your test at one of our special Collection Centres with one of our GPs or pathologists present.

RAST® (RadioAllergoSorbent Test)
The RadioAllergoSorbent Test (RAST®) is performed in the laboratory on a sample of your blood. It looks for the particular IgE antibodies your body produces in response to specific allergens.

Although RAST® tests are available for a wide range of allergens, Medicare Australia sets limits on the number, type and frequency of tests you can have. These restrictions can delay the results your doctor may need to help diagnose your allergy.

An extended RAST® panel can be performed for an additional fee. By choosing to have an extended RAST®  panel of tests performed, your doctor will have results for a wider range of allergen tests in just one visit.

New test available - Peanut Allergy Risk Assessment -  CLICK HERE

For parents, the diagnosis of peanut allergy is fraught with fear and apprehension; the chance that severe allergy may occur is of most concern. For doctors, the present tests significantly over-diagnose peanut allergy.

To help patients and clinicians, Sullivan Nicolaides Pathology offers the next generation of allergy tests, using recombinant peanut protein. When combined with traditional peanut RAST® (allergy) testing, this gives much greater knowledge about peanut allergy and the risk associated with it.

Phadia ImmunoCAP ISAC® - New advances in allergy testing are now available...
The Phadia ImmunoCAP ISAC® system is one of the most important recent advances in laboratory allergy diagnostics, that now allows us to determine, with a high level of accuracy and precision, specific IgE antibodies to a far wider range of allergens, including those that could not previously be tested for, and those present at low levels.

We can now test for 103 clinically important allergen molecules from 47 different allergens.

Through this extended range of tests we have the ability not only to identify the allergens to which you are sensitive, but also, in some cases, to estimate the severity of your reaction or your level of tolerance to certain foods.

It is a particularly useful test to assess whether a child may be growing out of their food allergies.

The test is performed on a routine blood sample that can be collected at any SNP collection centre. Results are not affected by medications.

There is no Medicare rebate for this test.
