Biomarker Reference · Cryptosporidium Ag
Cryptosporidium species Antigen (Cryptosporidium Ag) is a clinical biomarker used in microbiome-gut assessment. Enzyme immunoassay detects Cryptosporidium oocyst antigens in stool. It is measured in 1 laboratory test on BiomarkersLabs.com.
Enzyme immunoassay detects Cryptosporidium oocyst antigens in stool. This coccidian protozoan infects small-intestinal epithelium, causing watery diarrhoea that is self-limited in immunocompetent hosts but severe and persistent in immunosuppressed patients. Oocysts are small and easily missed on routine O&P; antigen testing markedly improves detection.
Cryptosporidiosis is an important differential in acute diarrhoea following exposure to contaminated water, in HIV/AIDS patients with CD4 counts below 200 cells/µL, and in other immunosuppressed states. Detection guides supportive care in immunocompetent patients and targeted antimicrobial or immune reconstitution strategies in immunocompromised hosts.
Reference ranges vary by laboratory and assay platform. Interpret in context of the issuing laboratory's stated range.
