LIT serum contains higher levels of IgG anti-IgE/IgE immune complexes and lower free IgE levels relative to AAD serum. a Levels of IgG₁ anti-IgE/IgE immune complexes were determined as described above. For naïve samples, undiluted serum was used. b Levels of free IgE were determined in samples with equal concentrations of total IgE as described above. For naïve samples, undiluted serum was used. n = 6–8 per group. *p < 0.05 vs naïve, ***p < 0.001 vs naïve, ^††p < 0.01 vs AAD, ^†††p < 0.001 vs AAD. ^ND none detected
