Cryptosporidium is a significant cause of diarrhea worldwide especially in children. Infection may end fatally in immunocompromised patients. Multi-attribute analysis was used to determine the lab utility of 4 diagnostics; coproscopy of AF stained fecal smear, fecal immunoassays by ICT and ELISA and copro-nPCR assay targeting Hsp90 gene, for detection of Cryptosporidium in stool of 250 Egyptian children (150 diarrheic and 100 nondiarrhaeic children). Also, to determine Cryptosporidium molecular prevalence. Cryptosporidium was an important enteric pathogen among both diarrheic and non-diarrheic study children with a clearly high prevalence of 16.4 % (n = 41). Conventional methods had perfect specificity (100 %) but couldn‘t be used as a consistent single detection method due to their lowered sensitivities. Multiattribute analysis ranked nPCR the highest test for lab use. Being the test with the best diagnostic yield, nPCR is a reliable diagnostic test and is going to replace conventional methods for reliable detection of Cryptosporidium.
