What are food intolerances?
Since food intolerances can affect inflammation, they may be a factor to consider in certain medical conditions such as:

Food intolerance is a reaction of the immune system to a specific food. Depending on the source, it may be called food hypersensitivity, type III food allergy or simply food intolerance. It involves IgG antibodies that bind to the protein of the food in question, called antigen. This immune complex (IgG-antigen) will accumulate in certain tissues of the body near or far away. The body then triggers an inflammatory process to eliminate these immune complexes. If these are present in too large a quantity (large quantity or frequency of ingestion of the food in question), the body cannot break the cycle and chronic inflammation sets in.
The sensitivity of an individual varies according to his or her genetic profile, the state of his or her immune system, digestive function, the quality of the gastrointestinal barrier, the composition of the microbiota (intestinal flora), the frequency and quantity of consumption of the food antigen, etc. Leaky gut is often associated with an increase in food intolerance and the intensity of symptoms.
Certain discomforts may indicate to a person that they are intolerant to certain foods. These discomforts may occur quickly or hours or even days after eating, making identification difficult. The physical manifestations may differ from one person to another or from one period to another for the same person. Food intolerances can affect your quality of life and long-term health.

* Food intolerances can be detected by analyzing a blood sample taken from a fingertip. The test consists of evaluating the importance of the presence of IgG associated
Available profiles
Food intolerances (hypersensitivities) are not a disease, but they can be the cause of many discomforts or aggravate certain symptoms related to diseases already present. They can be easily detected by analyzing a blood sample taken from a fingertip. The test consists of evaluating the importance of the presence of IgG associated with the foods tested in the blood. It takes a look at your diet over the last 3 months, so it is important to do it during a period when you have symptoms. If there are foods that you haven’t eaten in more than 3 months, know that it is unlikely that these are the foods that are giving you these symptoms. Therefore, in order to accurately assess your food intolerances, it is necessary to consume the suspected foods. Generally, 2 servings of these foods per week for the 2 or 3 weeks preceding the sample are sufficient for the formation of antibodies. If you have eliminated these foods for more than 6 months, you should eat 2 servings per week for 6 weeks before taking the sample.
DO NOT CONSUME foods that you suspect are responsible for severe reactions (e.g. hives, anaphylactic shock, difficulty breathing).
Different food profiles are available according to your personal needs.
Which profile should I choose?
It is important to choose the profile that best suits your eating habits and your budget. If you don’t eat meat, fish or seafood, the vegetarian profile is just right. If you are hesitating between the 120 and 220 profile, here is the list of foods that are present in the 220 profile and not in the 120. If your diet includes 4 or more foods from this list, perhaps the 220 profile would be the best option.

Lactose tolerance test
Clinique Prelev now offers the lactose intolerance test. The evaluation of lactose intolerance involves administering an oral dose of lactose solution to a fasting patient and monitoring their blood sugar levels at 0, 30, 60, 90, and 120 minutes. Therefore, a minimum of 2 hours should be allotted for the appointment. If the person is lactose intolerant, their body will produce only minimal increases in glucose, so this approach is commonly used in adult patients in regional hospitals. The test is performed by taking blood samples.
A prescription from your health care professional is required
* Please note that the test can only be performed on children over 55lbs (25kg).
