Additionally, we assessed plasmatic levels of immunoglobulins A (IgA) and E (IgE), as IgA has been used as a diagnostic tool in giardiasis [52,53], and levels of IgE may become modified by some intestinal parasites [54], and have been described as augmented in human giardiasis [55,56,57]. The gene discussed is CD79A; the disease is giardiasis.
