[Parasitological examination of stools: french ANOFEL/LABAC recommendations].

Parasitological examination of stools is a challenging analysis due to the diversity of parasites to be screened for, depending on the exposure context and patient background. Parasite detection is traditionally performed using direct wet mount and various concentration methods followed by microscopic reading, which requires expertise. The quotation of this analysis in the nomenclature of medical biology procedures has become obsolete due to the development of molecular biology techniques and epidemiological changes. Currently commercialized nucleic acid detection techniques, often in multiplex panels, should not be used without an understanding of their limitations in terms of the relevance of the panel of parasites detected and technical performance. These recommendations aim to guide biologists and COFRAC auditors regarding the implementation of parasitological examination of stools, the choice of techniques and their limitations, for optimal medical care.
