Abstract
A method and apparatus are provided for data management authentication in a clinical analyzer. The clinical analyzer includes a sensor for receiving a user sample to be measured and a processor for performing a predefined test sequence for measuring a predefined parameter value. A memory is coupled to the processor for storing predefined parameter data values. An authentication password is associated with each data transmission by the clinical analyzer and read by an associated computer system to validate each data transmission. The authentication password is generated by the clinical analyzer utilizing predetermined information in each data transfer.
