6.2 Phasing of development
The rate of development of any laboratory service is commonly limited by the availability of qualified and experienced personnel and the possibilities for further training.

Initially, it is prudent to concentrate on the development of chemical and physical techniques of analysis and testing, and to defer the introduction of microbiological and biological techniques to a later stage.
