Patient's Query

Hello doctor,

Could you please explain if this means I have an allergy to olive trees or ash plants (Fraxinus excel) or something else?


Welcome to icliniq.com.

We will pay close attention to your worries and address all your questions with utmost care.

Fraxinus excelsior is a common ash plant. It belongs to the olive family. Plants in the same family have shared antigens. If you are sensitive to one plant in the family, then you are likely to be sensitive to others also. Hence, the result means that you are sensitive to olives as well in addition to the Fraxinus excelsior plant.

Being sensitive does not mean you are allergic. Sensitivity does not always result in allergy. Sensitivity means you have circulating antibodies against that particular allergen. However, it may or may not result in an allergy to that particular antigen. Only when you are exposed to it in a particular format and quantity, you will develop an allergy to it. Skin prick test only measures sensitivity to specific allergens.

We need to infer the results based on your symptoms. What do you suffer from? Was the test done to check for aeroallergens or food allergens? The two are different with different symptoms. Kindly elaborate on your problems to us.

Please feel free to reach back to us if you have any further queries.

Thank you.

Same symptoms don't mean you have the same problem. Consult a doctor now!
