When your body doesn’t recognise a food as being safe for you, the symptoms can range from diarrhoea and constipation to nausea, vomiting and diarrhoeas.
A Food Allergy Test (FAST) is a test that can detect foods that cause food sensitivities.
It’s used to help you manage your symptoms and is part of a range of other tests including the Food Allergies Assessment Toolkit (FAT), the Food Sensitivity Test (FSET), the Personalised Food Allergic Test (PFAT) and the Foodborne and Other Allergy (FANAT).
While FAST is a good test, it isn’t a cure-all.
The test only measures the levels of antibodies to foods in your blood.
The Food Allergen Testing System (FATS) is designed to help test takers identify food allergies.
Food allergy testing can be done using either the Food Asthma Test (FAAT) or the Food Exposure Test (FEAT).FATS can be completed at your local pharmacy.
The FATS is a two-step process: the first step is to provide saliva samples.
Next, you’re asked to answer questions about your food allergy symptoms.
These can range anywhere from:Your symptoms may include:How long does it take for the symptoms to resolve?
Are they resolved with medication?
If you have an existing food allergy, what are the possible triggers for symptoms?
If your symptoms are worsening, can you identify the most likely triggers?
Are there any specific triggers you can avoid?
You will be asked to provide a blood sample at the time of your FAST test.
The tests are usually completed within 24 hours.
The FATS can also be completed with a urine sample, but urine tests can take longer than 24 hours to complete.
If your food is safe for eating, it may not be safe for the FATS test to take.
You should be able to eat food if you’re healthy, but it may be important to take a food allergy test in a more urgent setting such as a hospital, hospital ward, GP, GP surgery or nursing home.
If you can’t eat food, you may be able the FAST, FOAT or FEAT to test for a food sensitisation or food allergy.
