As a part of HL7 parser development, need to know whether the placer order and filler order number of multiple OBR segments in a HL7 message will be same.

Read theory about placer and filler order number in the internet. But was not able to find good examples.

Looking forward for answer with good examples.

As a part of HL7 parser development, I personally, would always expect that the placer order and filler order number fields will have different values for each OBR segment in a message. However, I believe it is common for these order numbers to be the same in all OBR segments within a message.

That being said if an ORU (result) message contains observations for a test that is a single specimen with multiple tests performed then you will have multiple OBR and OBX segments for each of the tests performed. In a case such as this the multiple tests could be performed by different laboratories causing different filler order number fields.

  • Thanks for your response. It was very helpful. "multiple tests could be performed by different laboratories" - Denotes that a single HL7 lab results message will contain the results from different test machines. Am I correct? If so can you please provide some examples. – Vidya Dec 14 '15 at 10:50
