what is HL7 message format?

Answer 1

HL7 is a specification for a health data-interchange standard designed to facilitate the transfer of health data resident on different and disparate computer systems in a health care setting. HL7 facilitates the transfer of laboratory results, pharmacy data and other information between different computer systems. HL7 is not designed to support the transfer of the entire patient record. HL7 does not support the transfer of image data (such as from a PACS).
