the IgE in blood serum testing is 1024 for my son aged 20 yrs... he has been showing the symptoms of dry cough for the last 3 yrs ... it is more severe in morning & bit less in evening... during day time it is on avg... the x- ray chest PA is normal as per report in 2010 &2013... coughing is relatively more during exam days suggest the possible diagonosis if any further testing is required. (is it allergy associated or something else..??)
Hi, High IGE levels associated with symptoms of cough indicate atop; there may be associated eosinophilic and also parasitic infection. It could also be caused due to asthma, but as there is only Chat Doctor.  Your son should be assessed by a pulmonologist for proper management. Stress is an important factor playing its part. Good luck.
