The application and limitations of immunodiagnostic techniques in parasitic infections

The application of immunodiagnostic techniques in the diagnosis of parasitic infections has been discussed in relation to the conditions operating in developing countries where multiple parasitism is common and diagnostic facilities are often limited. The uses and limitations of the tests for individual diagnosis and epidemiological studies have been highlighted. The filter-paper plasma modification of the IFA test has been identified as a technique that has an advantage over all the others and could be universally used with great success in many developing countries.
