Biomarker surrogates do not accurately predict sputum eosinophil and neutrophil percentages in asthmatic subjects

Conclusion: Despite statistically significant associations, Feno levels, IgE levels, blood eosinophil and neutrophil counts, FEV1 percent predicted, and age are poor surrogates, both separately and combined, for accurately predicting sputum eosinophil and neutrophil percentages.
