Heterophilic antibodies in sera from individuals without loxoscelism cross-react with phospholipase D from the venom of Loxosceles and Sicarius spiders

Table 2 Human IgG levels in serum samples from patients with and without loxoscelism

Serum samples	IgG ^a (mg/dL)	Reference range (mg/dL)	p-value^#
Loxoscelism group (n = 10)	1355 ± 117.1	710–1520	0.7445
Without loxoscelism group (n = 30)	1385 ± 36.14	710–1520	0.7445

^aValues of media ± SEM. Human IgG concentration in serum were determined by radial immunodiffusion (RID). ^# t-test; α = 0.05
