Testers can use these templates during validation to compare the expected value for each data element against the actual content of the message. The LOI and LRI templates are populated with data for the Virginia DCLS order and result message in order to demonstrate how laboratories can utilize this tool. It is expected that the laboratory will replace this data to reflect its own message values. The Building Blocks team developed a Message Validation Template for the LOI order message and the LRI result message. As further guidance, the Building Blocks team has populated a copy of each template with an example message.
