Serum aluminium in hyposensitized allergics

The concentration of serum aluminium was examined in hyposensitized subjects receiving subcutaneous injections of solutions of allergens precipitated with or adsorbed to aluminiumhydroxide and in non-hyposensitized allergies. No correspondence between the serum values and the quantity of aluminium mediated with the injections was found. It was concluded that the investigation did not incriminate this type of treatment in causing rising serum concentrations of aluminium.
