We then: (1) identified factors associated with high blood eosinophil counts (>75th percentile); and, (2) excluded subjects with these factors to estimate median blood eosinophil counts in a “healthy” sub-population (n=3641).We found that: (1) in the entire cohort, age ≤18 years (odds ratio [OR] 2.41), asthma (OR 2.05), current smoking (OR 1.72), positive skin prick test (OR 1.64), COPD (OR 1.56), metabolic syndrome (OR 1.41), male sex (OR 1.36) and obesity (OR 1.16) were significantly (p<0.05) associated with high blood eosinophil counts (binary multivariable logistic regression analysis); and had an additive effect; (2) after excluding these factors, in those older than 18 years, blood eosinophil counts were higher in males than in females (median 120 [5%–95% CI: 30–330] versus 100 [30–310] cells·µL−1, respectively) and did not change with age.Median blood eosinophil counts in adults are considerably lower than those currently regarded as normal, do not change with age beyond puberty, but are significantly influenced by a variety of factors which have an additive effect. These observations will contribute to the interpretation of blood eosinophil levels in clinical practice.FootnotesThis manuscript has recently been accepted for publication in the European Respiratory Journal.
