Functional Testing

We do functional testing at Auckland Skin Clinic. Depending on your presenting symptoms we may order blood tests, hormone tests or food allergy tests. Testing is not necessary in every case. It is used a tool to help detect the underlying cause of your condition or symptoms, to confirm deficiencies, assist treatment, and monitor progress.

We can do some tests in clinic such a blood type testing and food allergy testing. Others we order externally. We only order and perform tests that are scientifically validated.

Food Detective™ is a test for an immune response to food that can be performed in the clinic by your health practitioner. You don’t have to wait weeks to receive results from a testing laboratory.

Food Detective™ tests for IgG antibody reactions to 59 commonly eaten foods. The test is performed using a blood sample from a finger-prick that is diluted then added to the Food Detective™ testing tray (containing small spots of food protein extracts). In subsequent steps, the use of detector and developer solutions identify the presence of food antibodies through the appearance of one or more blue spots on the tray.

IgG antibody reactions indicate food intolerances rather than a classical food allergy (such as peanut or shellfish allergy), which is usually characterised by an immediate and often severe reaction of the immune system to exposure to a specific food.

So what exactly is food intolerance?

The complex way food affects our everyday lives is an emerging area of understanding, and diagnosing the cause of symptoms which seem to be ‘unexplained’ is often difficult.

Although not life threatening, food intolerance should never be underestimated as its impact on sufferers can be significant, sometimes affecting their ability to live normal healthy lives. The incidence of food intolerance is extremely wide and it is estimated that 45% of the population could be affected. Many people with food intolerance experience more than one symptom. Symptoms can often be vague and the root cause of the problem, food, is not always correctly diagnosed. Sufferers often complain of seeming to be in a ‘fog’, feeling bloated and being tired all the time.

Essentially food intolerance is your body’s abnormal reaction to certain foods which can manifest itself in a number of ways. Some people will have one symptom such as a severe headache whilst others will be unfortunate to experience irritable bowel syndrome, migraine and skin or respiratory conditions. Realising that your food is a catalyst for particular symptoms is not easy when, unlike the immediate reactive symptoms of food allergy, food intolerance symptoms often appear hours or even days later. In fact many food intolerance sufferers have commented post diagnosis and after having removed their problem foods that they realise they had been experiencing minor symptoms as a result of intolerance for their entire lives.
