|SOME GUIDELINES FOR ESTABLISHING A TUBERCULOSIS
|N Naganathan: NTI Newsletter 1974, 11, 32-34.
The issues to be addressed while establishing a
tuberculosis culture laboratory are discussed in the paper. Primarily
the following questions are to be considered: (1) Is it absolutely
essential to have a tuberculosis culture laboratory? (2) Will it
be big or small? (3) Are there adequate means to continue work in
terms of finance, staff, equipment & specimens and (4) Is there
a possibility of taking up any other type of bacteriological work,
if necessary? Unlike other bacteriology laboratory, a tuberculosis
laboratory has some unique features. Due to the slow growth of the
organism, cultures need to be incubated for a long time i.e., 8
10 weeks. So an incubator room is required. More number of
glassware are needed. Test tubes with cotton plugs are unsuitable
as they are likely to dry up. Hence screw capped tubes or McCartney
bottles are required to facilitate long incubation of cultures.
For performing identification tests, incubators with varying
temperatures, i.e., 23, 37, 44, are to be provided. Plenty of
cold storage space is needed to stock cultures, media, etc.
The requirement of staff and organisation of work
depends upon the number of specimens handled. If 50 specimens per
day are likely to be processed, 5 lab technicians, 3 lab attendants,
1 sweeper and 1 bacteriologist are necessary. Once laboratory is
opened, maximum benefit should be derived by getting adequate number

|COST OF ESTABLISHING AND OPERATING A TUBERCULOSIS

This paper deals with the cost of establishing
and running a bacteriological laboratory in State Tuberculosis Centres
under the National Tuberculosis Programme, and the cost of various
examinations to be undertaken in such a laboratory. A knowledge
of the cost will enable proper planning and judicious utilization
of the resources. Further, when services are rendered to private
individuals or institutions, the charges for different examinations
can be levied on a rational basis. The place of smear and culture
examinations under the programme, the implications of establishing
a culture laboratory, the limitations of cost worked out, have been
discussed. A plan of the laboratory building is also provided.
The cost has been worked out presuming that about
12,000 specimens per year are likely to be received, of which 25%
might turn out to be positives. Non recurring cost was estimated
to be Rs.1,07,724 and annual recurring cost would be Rs.49,709.
Factors that contribute to the cost structure are overheads,
cost of material and labour. In addition, certain essential
facilities like cold room, incubator room, gas supply, washing and
sterilisation etc., add to the cost. (i) staff-bacteriologist-1,
lab technicians-4, lab attendants-3 and registration clerk-1; their
salaries, (ii) building-rent (iii) electricity (iv) furniture (v)
equipment and supplies (vi) water charges had all been taken into
consideration. The cost of one smear examination was estimated to
be Rs.0.54 and that of culture and sensitivity test Rs.9.43.
