ISAC Test: 112 Allergy Tests in one tiny blood sample!

A Private Allergy ISAC test can test for 112 allergies from one tiny blood sample!

The ISAC test is a blood test that uses microchip technology to detect specific IgE antibodies to food and airborne allergens (this test uses method called ELISA with a special reader; it replaced the test previously called RAST). It allows  simultaneous measurement of specific antibodies to multiple allergen components in a single test, using only a few µl of serum or plasma. The allergens are pre-selected and include the most relevant specie specific and cross-reactive markers.

ISAC test London Allergy and Immunology Centre

A combination of innovative biochip technology with cutting edge research in molecular allergology has resulted in ImmunoCAP® ISAC – the most advanced in vitro diagnostic test for simultaneous measurement of specific IgE antibodies to a broad spectrum of allergen components.

This test is now available all over the UK in England, Scotland, Wales and Northern Ireland as well as for some international customers with the new self finger prick collection and sample in the post technology.

Allergy testing is easy now there is even no need to travel to the clinic to have this test done!

You will receive a report with interpretation of your results from one of our Allergy and Immunology consultants!

Please e-mail us for details

In London you can attend our adult or paediatric allergy clinic or laboratory where a blood sample can be taken.

The specific IgE chip delivers results for over a hundred components from more than 50 allergen sources

(see the list of allergens below).

The ImmunoCAP® ISAC test provides a large amount of allergen specific IgE  antibody information – the big picture – in a single step. This enables
patient investigations that require less time and resources. As a result, effective and optimized management can be started earlier, which in turn leads to improved patient health and quality of life. This test is relatively inexpensive comparing with the price of testing of sIgE to allergens individually.

How to have this test done:

If you are in London and want to be seen by an allergy consultant, or if you want your child or baby to be seen by our paediatric allergy consultant and want to ask the doctor to consider allergy testing blood test, please book an appointment on-line or call 020 314 33449.

If you live at a distance from London, or for any reason cannot attend a face-to face appointment, please start with filling in an ISAC allergy symptoms questionnaire, which will be reviewed by one of our allergy consultants. Please proceed to bank transfer payment of the invoice that you will receive by e-mail after you send your questionnaire. You will receive a sample collection pack from the lab (as shown in video) or if you opted for a collection in London you can attend the lab with printed request form for sample collection (the request form will be sent by e-mail after your payment).

Finger prick collection is not suitable for small children and babies, sample needs to be taken by a trained healthcare professional (our lab can provide necessary materials on request if you are located at a distance from London), or in London you can attend the lab with our form where the sample will be collected Mo-Fri 7am-7pm and Saturday 9am-5pm.

Your results will be ready in about 2 weeks (we aim for 7 days). These will be reviewed by one of our allergy consultants in conjunction with your questionnaire, then sent to both you and to your GP (if you opted for this in the questionnaire).

If you have any further questions, need , a consultation, treatment, or if any problems are identified throughout this testing process, we would be happy to book you an appointment to meet with one of our specialists.
