Abstract:
The diagnostic usefulness of the passive haemagglutination test with B. pertussis endotoxin was compared with ELISA test prepared by Biomedica firm performed with protein antigens of B. pertussis (pertussis toxin and fibrillary haemagglutinin) making possible the identification of antipertussis antibodies class IgA, IgM and IgG. The comparison was done in 133 serum samples obtained from 124 children with the clinical diagnosis of pertussis certain or suspected. Both tests were found to be useful in the laboratory diagnosis of pertussis. The particular diagnostic usefulness was confirmed of the detection of antibodies class IgA against pertussis in children aged over 6 months.

Enzyme-Linked Immunosorbent Assay
There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen. Enzyme-substrate reaction allows the antigen to be visualized or quantified.
