My son, age 12 has had allergies, asthma,eczema and slow weight gain,GI symptoms, etc. his whole life. He was adopted as an infant and we have no bio information. He was diagnosed with an eosinaphilic disorder this last year. This is where food allergies cause inflamation in the esophagus and intestines with damage from an overabundance of eosinaphils. He is on a very limited diet for this.
He has always had issues with breathing and seems to always have a lot of mucus coming out of his sinus's and throat. He has a lot of nausea from the drainage. He was just treated with antibiotics for one month for a chronic sinus infection. At followup last week the ent said that the infection is cleared, yet he is still getting jugh amounts of mucus with the sinus washes, twice daily and coughing and wheezing with his asthma. He coughs up plugs of mucus several times daily. After getting it up his wheezing is better and he can sleep better. He gets out of breath easy and has had to quit every sport he has tried because of this. We have been told that it is from the environmental allergies and asthma.
I am just suspecting more than that is going on. He has had several rounds of steroid bursts this year. His asthma suddenly got worse in the last few months than it has ever been. Yet his peak flow readings do not increase that much with inhalers. His lung function tests have never been over 80% even with treatments. We have never had a good explanation for that.
I asked my allergist yesterday to order a test for CF. She has called it in and we will be going in for the blood test. Is the blood test as accurate as the sweat test? How long does it take to get test results?
Are we barking up the right tree? Can we trust the tests, positive or negative? I'm really afraid to even go in for this test! We need answers for the best treatment though. I would love to hear from others that were diagnosed at an older age. I thought this was something that was always caught at birth! I have read that is not the case.
Thank you for any help or dvice you may have.
