## Who's at risk? - Those whose parents suffer from dog and pet [allergies](https://ul.orna.me/KOge/librarydisease?id=21). - Those who have already experienced an allergic reaction to other antigens (pollen, dust mite, food, etc.). - Those who suffer from disorders of digestion and assimilation of food, with an imbalance of intestinal microflora. ## How to check if you are allergic It is worth doing a general blood test with leukoformula, total [IgE](https://ul.orna.me/KOge/librarybiomarker?id=103), IgE to the epithelium, and saliva of the dog.

However, you should keep in mind that these tests may not be informative if ===there has been no contact with dogs for a long time. For a more accurate diagnosis, you can try living next to the dog for a while (for example, asking friends who have a dog to visit periodically or even leaving it with you for a few days).
