All the 108 healthy samples from various parts of India gave negative reaction, while 157 out of 161 diseased samples gave positive reaction. The 44 of the ISO apparently healthy samples (with no visual symptoms) tested, which gave positive reaction, will be observed for the development of symptoms to assess the sensitivity and diagnostic value of this test.enArticle
