A total of 90 stool samples were tested. Diagnosis of giardiasis by ELISA for copro-Ag detection was positive in 46 (51.1%) patients whereas by direct stool analysis after formol ether concentration G. lamblia was detected in 38 (42.2%) patients only. ELISA technique for detection of Giardia copro-antigen had a sensitivity of 97.3% and a specificity of 82.6% with PPV of 80.4% and a NPV of 97.7%. | | Language | eng | | Pub Type(s) | Journal Article
