The tests approved by
the Revised National Tuberculosis Control Programme (RNTCP) for
diagnosis of TB include sputum microscopy, X-ray Chest, Solid & Liquid
Culture methods and Rapid molecular tests. Available evidence indicates
that besides the tests mentioned above the private sector heavily relies
on serological tests for diagnosis of TB.
As per the WHO recommendation, the currently available commercial
serological tests provide inconsistent and imprecise estimates of
sensitivity and specificity and these tests should not be used for the
diagnosis of pulmonary and extra-pulmonary TB.
The Government of India has imposed a ban on the manufacture, sale,
distribution, use and import of serological diagnostic tests for TB in
India as per the Government of India Gazette Notification Nos. G.S.R.
432 (E) and G.S.R. 433 (E) dated 7th June 2012.
RNTCP already has NGO/PP (Private Practitioner) Schemes in place for
involvement of private sector such as the Designated Microscopy Centre
Scheme; Treatment Adherence Scheme; Advocacy, Communication & Social
Mobilization (ACSM) Scheme etc. to detect TB and cover the patients
receiving treatment in the private sector.
The RNTCP has already approved newer rapid molecular diagnostic test for
timely and accurate diagnosis of TB in the country. Besides these,
Community involvement and Advocacy, Communication & Social Mobilization
(ACSM) activities are being undertaken for early referral of TB suspects
for diagnosis of TB.

Welfare Shri Abu Hasem Khan Choudhury in written reply to a question in
the Lok Sabha today.
