Limitations
This assay does not provide diagnostic proof of lack of protection again diphtheria or the presence of absence of immunodeficiency. Results must be confirmed by clinical findings and other serological tests
The diagnosis of tetanus is by clinical observation. A positive wound culture for the agent of tetanus, Clostridium tetani, may support, but does not confirm, the diagnosis. Toxin assays for tetanospasmin may be useful but are only available in a few laboratories
The results obtained from this assay are not diagnostic proof of lack of protection against tetanus or the presence or absence of immunodeficiency
