MSH [1..1] [R]
MSH.1 [Field Separator] [1..1] [R] (ST)
Definition: This field contains the separator between the segment ID and the first real field, MSH-2-encoding characters. As such it serves as the separator and defines the character to be used as a separator for the rest of the message. Recommended value is |, (ASCII 124).
MSH.2 [Encoding Characters] [1..1] [R] (ST)
Definition: This field contains the four characters in the following order: the component separator, repetition separator, escape character, and subcomponent separator. Recommended values are ^~\& (ASCII 94, 126, 92, and 38, respectively). These encoding characters is valid only for pipe-and-hat encoding.

MSH.4 [Sending Facility] [1..1] [R] (HD) { Table : 0362-Facility }
Definition: This field further describes the sending application, MSH-3-sending application. ITK compliant systems use 3 characters ODS code for NHS organization. 5 Character codes may also be used when there are more than one sending facilities within NHS organization or this field is used to carry data at more granular level.
MSH.5 [Receiving Application] [1..1] [R] (HD) { Table : 0361-Application }
Definition: This field uniquely identifies the receiving application among all other applications within the network enterprise. Where the message is being broadcast by PAS to a number of consumer systems via the toolkit, this field should be populated with 'ROUTE' to indicate that the toolkit will take responsibility for onward routing.
MSH.6 [Receiving Facility] [1..1] [R] (HD) { Table : 0362-Facility }
Definition: This field identifies the receiving application among multiple identical instances of the application running on behalf of different organizations.

MSH.10 [Message Control ID] [1..1] [R] (ST)
Definition: This field contains a number or other identifier that uniquely identifies the message. The receiving system echoes this ID back to the sending system in the Message acknowledgment segment (MSA).
MSH.11 [Processing ID] [1..1] [R] (PT)
Definition: This field is used to decide whether to process the message as defined in HL7 Application (level 7) Processing rules. The first component defines whether the message is part of a production, training, or debugging system.

Definition: This field is matched by the receiving system to its own version to be sure the message will be interpreted correctly.
MSH.13 [Sequence Number] [0..1] [O] (NM)
Definition: A non-null value in this field implies that the sequence number protocol is in use. This numeric field is incremented by one for each subsequent value. In a multi-hop environment, it is possible that messages may be received out of sequence. This number can be used in conjunction with the Date/Time Value to assist in the identification of messaging which happens out of sequence. Further detail on this can be found in the accompanying document 01 - ITK - Toolkit Architecture Overview.

OBX [0..*] [O]
OBX.1 [Set ID - OBX] [0..1] [O] (SI)
Definition: This field contains the sequence number.
OBX.2 [Value Type] [0..1] [C] (ID) { Table : 0125-ValueType }
Definition: This field contains the format of the observation value in OBX. It must be valued if OBX-11-Observ result status is not valued with an `X". If the value is CE then the result must be a coded entry. When the value type is TX or FT then the results are bulk text. Defines the value type for the data to be collected in Observation Value (OBX.5). Refer to latest version of HSCIC ITK HL7 V2 Reference Tables - Table 0125.
OBX.3 [Observation Identifier] [1..1] [R] (CE)
Definition: This field contains a unique identifier for the observation.
OBX.4 [Observation Sub-Id] [0..1] [O] (ST)
Definition: This field is used to distinguish between multiple OBX segments with the same observation ID organized under one OBR. For example, a chest X-ray report might include three separate diagnostic impressions. The standard requires three OBX segments, one for each impression. By putting a 1 in the Sub-ID of the first of these OBX segments, 2 in the second, and 3 in the third, we can uniquely identify each OBX segment for editing or replacement. This field is not relevant in ADT messages.
OBX.5 [Observation Value] [0..*] [O] (VARIES)
Definition: This field contains the value observed by the observation producer. The length of this field is variable depending upon value type. See OBX-2 Value type in International HL7 v2 specifications.
OBX.6 [Units] [0..1] [O] (CE) { Table : ZU038-Units }
Background: When an observation's value is measured on a continuous scale, one must report the measurement units within the units field of the OBX segment.
OBX.7 [References Range] [0..1] [O] (ST)
Definition: When the observation quantifies the amount of a toxic substance, then the upper limit of the range identifies the toxic limit. If the observation quantifies a drug, the lower limits identify the lower therapeutic bounds and the upper limits represent the upper therapeutic bounds above which toxic side effects are common.
OBX.8 [Abnormal Flags] [0..1] [O] (IS) { Table : 0078-AbnormalFlags }
Definition: This field contains a table lookup indicating the normalcy status of the result. Refer to latest version of HSCIC ITK HL7 V2 Reference Tables - Table 0078.
OBX.9 [Probability] [0..1] [O] (NM)
Definition: This field contains the probability of a result being true for results with categorical values. It mainly applies to discrete coded results. It is a decimal number represented as an ASCII string that must be between 0 and 1, inclusive.
OBX.10 [Nature of Abnormal Test] [0..1] [O] (ID)
Definition: This field contains the nature of the abnormal test.
OBX.11 [Observation Result Status] [1..1] [R] (ID)
Definition: This field contains the observation result status. This field reflects the current completion status of the results for one Observation Identifier.
OBX.12 [Date Last Observation Normal Value] [0..1] [O] (TS)
Definition: This field contains the changes in the observation methods that would make values obtained from the old method not comparable with those obtained from the new method.
OBX.13 [User Defined Access Checks] [0..1] [O] (ST)
Definition: This field permits the producer to record results-dependent codes for classifying the observation at the receiving system.
OBX.14 [Date/Time of the Observation] [0..1] [O] (TS)
Definition: This field is required in two circumstances. The first is when the observations reported beneath one report header (OBR) have different dates/times. This could occur in the case of queries, timed test sequences, or clearance studies where one measurement within a battery may have a different time than another measurement. It is also needed in the case of OBX segments that are being sent by the placer to the filler, in which case the date of the observation being transmitted is likely to have no relation to the date of the requested observation.
OBX.15 [Producer's ID] [0..1] [O] (CE) { Table : ZU025-ProducersID }
Definition: This field contains a unique identifier of the responsible producing service.
OBX.16 [Responsible Observer] [0..1] [O] (XCN)
Definition: When required, this field contains the identifier of the individual directly responsible for the observation (i.e., the person who either performed or verified it). In a nursing service, the observer is usually the professional who performed the observation (e.g., took the blood pressure). In a laboratory, the observer is the technician who performed or verified the analysis.
OBX.17 [Observation Method] [0..1] [O] (CE) { Table : ZU021-ObservationMethod }
Definition: This optional field can be used to transmit the method or procedure by which an observation was obtained when the sending system wishes to distinguish among one measurement obtained by different methods and the distinction is not implicit in the test ID.
OBX.18 [Equipment Instance Identifier] [0..1] [O] (EI)
Definition: This field identifies the Equipment Instance (e.g., Analyzer, Analyzer module, group of Analyzers, etc) responsible for the production of the observation.
OBX.19 [Date/Time of the Analysis] [0..1] [O] (TS)
Definition: This field is used to transfer the time stamp associated with generation of the analytical result by the instrument specified in Equipment Instance Identifier.
