Urinary antingen detection for diagnosis of hydatid disease

Hydatid antigen was demonstrated for the first time in urine of patients with hydatidosis by coagglutination test [Co-A]. Urinary antigen was detected in all Co-A positive serum corresponding samples of surgically confirmed hydatid disease. The sensitivity and specificity were 100% in urine compared with the corresponding serum samples. These results clarified that the use of Co-A test for the detection of hydatid antigen in urine is an easy, simple, rapid, noninvasive and efficient method for the diagnosis of hydatidosis
