I am coughing intermittently for about 5 months now, is this an allergy?

I am coughing intermittently for about 5 months now, my doctor advised me to get an allergy test done. Which I did.
The IGE immunoglobin serum test which I made came back with a value of 515 and the laboratory reference value is <65. Does this mean I have allergies- that I am allergic to something? I would like to know if this indicates that there is a problem with me? What do I need to do now? Is there medication that I need to take? I am a 35 year old woman. I never had any problems before. Don't take any medication whatsoever. Please let me know as soon as possible. Thanking you and your team ahead of time. Regards (...)
