<h3>Special Instructions</h3><p>None</p><h3>Description</h3> <p>The purpose here is to test the transaction LAB-1</p> <p>There are 3 possible messages. At least one of the three pairs shall be supported</p> <ul> <li> OML^O21: laboratory order message. This is a battery-centric structure: It contains a list of ordered batteries, a list of specimens underneath each battery, and a list of containers underneath each specimen. This structure implies duplication of specimen/container information whenever two batteries use the same specimen. It is more appropriate for ordering batteries that need several specimens (e.g. creatinine clearance, glucose tolerance test). </li> <li> OML^O33: Laboratory order for multiple orders related to a single specimen. This is a specimen-centric structure providing for each specimen a list of containers and a list of batteries (ORC/OBR segment groups) using this specimen. The batteries are not related to the containers. </li> <li> OML^O35: Laboratory order for multiple orders related to a single container of a specimen. This message structure provides for each specimen a list of containers, and for each container the list of batteries that are to be performed on that container. This structure is more appropriate when the ordered batteries are sorted by container.</li> </ul> <h3>Evaluation</h3>
