Abstract: A data interface which is capable of receiving test information from a variety of biological fluid testing instruments employs first and second processes. The first process determines the type of data which is provided by analyzing the format of the test information using a master rules file. Once the type of the source is identified, the first process passes the data and a set of rules to use to parse the data to the second process. The second process extracts the test data from the information provided by the testing instrument using the set of rules identified by the first process. Furthermore, if the test information is received in pieces the present invention can marry the pieces to provide a complete data set to be stored in the database.
