What is HL7v2?

HL7 version 2 (HL7v2) is a widely implemented standard for exchanging clinical and administrative data between healthcare information systems. It defines a set of messages that enable different systems to communicate, such as patient demographics, lab results, and orders. It's commonly used for integration within hospitals and other healthcare settings.
