Depending on how severe your allergy is, consuming a trigger food will nudge your body into a response that can involve:
Food allergies and intolerances can occur due to problems in different parts of our body’s immune system. Speedoc offers two types of diagnostic tests for food allergies:
lgE Skin Prick Test
lgG Food Allergy Test
If you have an acute reaction to a certain food, you could have an lgE mediated allergy. The reaction occurs within seconds or minutes of consuming the trigger food and is potentially life-threatening. Symptoms include sever swelling, breathing difficulty, rash, itch, and/or anaphylactic shock.
If your symptoms are less dangerous, you might have a non-lgE mediated allergy such as an lgG allergy. Some symptoms include bloating, nausea, or stomach discomfort. These symptoms can appear for up to three days after consumption of the trigger food but it is this delay in reaction that makes it difficult to pinpoint the trigger foods. An lgG allergy test helps to localise and limit the food suspects.
In place of the conventional skin prick test, all we need is a blood sample. We will run diagnostic tests on a sample of your blood and the results will be ready in four to six weeks.
Prior to the test, before your blood is drawn, you will have to:
Once the results are ready, you will receive a report containing individual results for all tested foods.
A Speedoc doctor will schedule a video consultation to explain the results and provide advice on your diet to alleviate some of your allergy symptoms. You will also receive a handy card summarising all the foods you are allergic to.

Speedoc’s food allergy test offers 95.8% accuracy when determining the allergen and predicted severity of the allergic reaction. The test allows for component testing in food allergies. This means the lab can determine the exact protein in a particular food that you may be allergic to and its corresponding allergic reaction.
Reduced exposure and risk
Processing your blood sample in a sterile laboratory eliminates any possibility of an allergic reaction, which is often observed in a skin prick test.
A blood allergy test is beneficial for those who have too much sensitivity for a skin prick test and is perfect for those who are concerned regarding the repercussions of undergoing a skin allergy test.
Undergoing a blood allergy test allows you to continue taking antihistamines. This is because blood tests are not affected by medication. The skin, on the other hand, becomes less reactive with antihistamine in the system and would produce less accurate results in a skin prick test.
If you rely on antihistamines, this would be the most suitable test.
Suitable for children
The food allergy test is suitable for children 12 years and above.
Reduced exposure and risk
Our medical professional will come to your home to take only your blood sample.

A food allergy is an immune system reaction that can affect organs in the body and cause dangerous health conditions. Conversely, food intolerance occurs in the digestive system and can be managed by consuming the particular food in smaller quantities.
Depending on the package you choose, peanuts (and other seeds and nuts) are foods that our packages test for.
You may feel sick, nauseous or bloated after eating foods that contain gluten. Gluten intolerance is also called non-celiac gluten sensitivity, and is not the same as celiac disease or a wheat allergy.
Lactose intolerance is the body’s inability to digest lactose. The food allergy tests cannot look for the enzyme that is required to digest lactose, hence will not be able to determine whether you are lactose intolerant. This test will inform you how sensitive you may be to dairy products.
A food allergy test can help to find out whether you have a true allergy or sensitivity to a food.
The food allergy test is suitable for children 11 to 12 years old, however, you can enquire with us if your child is not afraid of the blood-taking process.
Chicken egg is one food that our packages can test for. Depending on the package you choose, other types of eggs can be tested too.
Depending on the package you select, peanuts (and other seeds and nuts) are foods that our packages test for.
Food allergies in adults do happen more often than you think. If you notice or feel any discomfort such as vomiting, stomach ache, hives or difficulty swallowing after eating certain foods, you may be having an allergic reaction.
You are required to fast for at least 2 hours prior to your test.
You will also need to avoid oily food and fatty foods 8 hours before your blood is drawn.
