AB  - Microbiological monitoring of “Clean rooms” generates a large number of results, which are used, in the first instance, to determine that product or patient have not been exposed to an unacceptable risk of contamination. However, these results can also be used for trend analysis and retrospective event marking by means of the Cusum Technique. A computer application is described which uses this technique and which converts the data to a graphical output. The application of the graphs obtained to the control of the clean room environment is discussed.
