TABLE 2.
Correlation of sIgE results and prick test results of 2948 patients. Patients were classified into four groups: sIgE extract positive, prick positive (“true‐positive results”); sIgE extract negative, prick negative (“true‐negative results”); sIgE extract negative, prick positive (“false‐negative sIgE or false‐positive prick test”); and sIgE extract positive, prick negative (“false‐positive sIgE or false‐negative prick test”). Pollen (mean) states the average percentages of all pollen investigated.
