Major Pollen Allergen Components and CCD Detection in Bermuda Grass Sensitized Patients in Guangzhou, China.

The highest positive rate of pollen allergen components was Cyn d 1 in Bermuda grass sensitized patients in southern China. Most patients were sensitized to CCD alone, and CCD may have less interference in the detection of Cyn d 1, Art v 4, Phl p 1 and Phl p 12. The sensitization patterns of pollen allergen components varied in different ages and diseases, and the diagnostic strategy of pollen allergen needs to be considered in the future.
