The survey of the results of the control quality in Parasitology and Mycology showed in general an improvement in the correct diagnosis for the specimen analysed (preparations of parasites, smears, stools, sera, fungal cultures). The wrong diagnosis of Ascaris lumbricoides eggs in stools diminished from 5% to 1.5%. The trichrome Gomori-Wheatley stain technic on smears in PVA was introduced. 16 reference or national standards sera for the parasitological serology, including 6 for toxoplasmosis and one for candidiasis were established. The increasing number of participants (more than 4,000) and particularly for the serology of toxoplasmosis showed the interest of the biologists for the quality of their tests.
