The Order Result Tracker should store the observation result and its associated reference range. In case the Order Result Tracker offers the capability to compare results of the same observation over different requests, it should then associate each result with its associated reference range. 7.4.2.12 Retained for backward compatibility only 7.4.2.13 Required if available This field should be valued when the OBX-5 field (Value field) is also valued. In very exceptional case this information may be unknown by the Order Filler (case the test is transmitted in a reference lab and observation date and time is not returned together with the result), this field can be null and the Order Result Tracker should not generate an error. 7.4.2.14 Retained for backward compatibility only Required if available This field is required in case the observation was not produced by the sending organization 7.4.2.15 This field is required when the observation result status (OBX-11) is valued with "D" or "R" or "P" or "F" or "C" or "X" and the Producer's ID field is not valued. It should contain the identity of the observer that causes the change of the observation result status. Only the first component (ID number) of this field is necessary, provided that it is possible to retrieve the full identity of responsible person in the Order Filler system with this only ID number. 7.4.2.16 Retained for backward compatibility only Retained for backward compatibility only 7.4.2.17 Although this information should be available at the Order Filler level, this field should not be used in this first version of the Laboratory Technical Framework 7.4.2.18 Since the OBX-18 field should not be used; this OBX-19 field is pointless. 7.4.2.19 Retained for backward compatibility only Reserved for harmonization with V2.6 7.4.2.20 Reserved for harmonization with V2.6 7.4.2.21 Reserved for harmonization with V2.6 7.4.2.22 7.4.2.23 7.4.2.24 deprecated as of v2.5 Retained for backward compatibility only Retained for backward compatibility only This field is required when the observation result status (OBX-11) is valued with "D" or "R" or "P" or "F" or "C" or "X" and the Producer's ID field is not valued.
