To evaluate the rapid immuno-chromotographic assay ICT based on antigen 38
Kda of Mycobacterium tuberculosis, sera was collected from 245 persons, 111 of
them were pulmonary TB patients, 69 extrapulmonary, 25 having non TP
respiratory diseases, an
d 30 healthy control persons.
The diagnosis were based on usual testes such as signs and symptoms, X-ray,
smear and biopsy as well as the using of the serological test ICT the results were
as follows:
When pulmonary TB smear positive ICT was positive in 50 of 55 patients
(sensitivity 91%) whereas in pulmonary TB smear negative, sensitivity of ICT was
86 % (48/ 56). The sensitivity of the assay in extra-pulmonary TB patients was
74% (51/69) and the sensitivity of the test in all TB types was 83% (149/ 180) and
specificity of the test in nonTB pulmonary diseases were 96% and 100%in healthy
persons.
