[Technics of detection and diagnosis of African trypanosomiasis in humans].

The authors review the most recent and sophisticated laboratory techniques for screening and diagnosis of human african trypanosomiasis. Immunological screening: indirect immunofluorescence, card agglutination test. Parasitological diagnosis: hematocrit centrifuge technique, miniature anion exchange/centrifugation, cerebrospinal fluid centrifugation. For each of these techniques, the authors deal successively with principle and method, interest, possible applications.
