Objective: To investigate the relationship between Dermatophagoides pteronyssinus(Dp) and Dermatophagoides farinae(Df) specific IgE in the serum or local secretion of perennial allergic rhinitis (PAR) patients.
Method: The serum and nasal secretion of suspected PAR patients were collected, then the concentration of mite sIgE in them were measured and analyzed.
Result: The concentration of Dp and Df in serum or the local secretion was almost the same. The relationship between the two mite sIgE concentration and logarithm is good both in the serum or the local secretion(relative coefficient is about 0.97).
Conclusion: The sIgE amount of the two mite is very similar in the body of the suspected AR patients, so only one kind of sIgE is needed to be measured to reflect the allergic situation in clinic.
