Interestingly, no significant correlations between metals and Ig in asymptomatic COVID‐19 were identified, however higher IgA levels were not significantly associated with lower Zn (Rho = −0.46, p = 0.052), higher Cu was associated to higher IgG (Rho = 0.41, p = 0.09), and IgM (Rho = 0.42, p = 0.084). The gene discussed is CD40LG; the disease is COVID-19.
