Evaluation of a novel automated allergy microarray platform compared with three other allergy test methods

https://onlinelibrary.wiley.com/doi/full/10.1111/cei.12721

All patients were tested with four allergy test methods (SPT, ImmunoCAP, Microtest and ISAC 112) and a total of 3485 pairwise test results were analysed and compared. The four methods showed comparable results with a positive/negative agreement of 81–88% for any pair of test methods compared, which is in line with data in the literature.
