While I have no idea about HL7 the intent of the fields is

clin.lab_request.request_id:    filled in by GNUmed/praxis staff and hopefully 
returned by the lab

clin.lab_request.lab_request_id:        invented by the lab for internal (?) 
use and transmitted to the praxis
                                    often useful when phoning in for 
clarification
