This has prompted the Union Health ministry to write to the state health department seeking special exemption for procuring and using alcohol and spirit for uninterrupted diagnostic services.
There is a scarcity of ethyle alcohol which is used to conduct such tests in the laboratories, including those in government facilities, according to Dr Jagdish Prasad, Director General of Health Services, Ministry of Health.
In his letter to Principal Secretary, Department of Health in Bihar, Prasad said prompt diagnosis and appropriate treatment is essential for a successful tuberculosis control programme and its diagnosis at peripheral levels continues to be performed primarily by smear microscopy.
The reagents required for smear microscopy (both Ziehl Neelsen and Fluorescent staining) include absolute alcohol. Spirit is also needed for the lamps used for making smears. Cleaning of the plungers of the CBNAAT, as part of monthly maintenance also requires alcohol, he said in the letter.
Freshly prepared 70 per cent alcohol is also required at all levels for surface disinfection.
"With the alcohol ban imposed in Bihar, the laboratories are facing difficulty in procuring alcohol and this has affected the diagnosis of tuberculosis in the state," Prasad said in the letter, dated June 29.
"In view of the above and in public interest, special exemption for procuring and using alcohol and spirit for uninterrupted diagnostic services under the Revised National Tuberculosis Control Programme (RNTCP) is required," he said.
There are 736 microscopic labs besides 38 special labs for detecting TB.
"Bihar government should abolish ban on the use of alcohol and spirit specially in laboratories and hospital setups. Alcohol and spirit are used for preparation of reagents for microscopy. This is essential for microscopy test.
On several occasions, the chief minister highlighted that the prohibition has had positive impact in the state, with road accidents going down and people saving more money.
