title: [Identification and generalization of classes of public health laboratory detection activities].
abstract: OBJECTIVE
  To identify and generalize classes of public health laboratory detection activities and to discuss the method of identification and generalization of classes of Public Health Conceptual Information Model.
  
  
  METHODS
  At first, materials should be collected from consulting literatures and experts, referring to the existing system. Then, identification and generalization of classes are got for business process analysis, writing description documents, summing up important conceptions and activities, By use-case analysis, use-case diagram and tabulation of important conception and activities and reference to PHCDM, a structural diagram of classes is constructed.
  
  
  RESULTS
  A structure diagram of classes of public health laboratory detection activity is given.
  
  
  CONCLUSIONS
  This is a feasible method in identification and generalization of classes of public health laboratory detection activities.
