7.1.4 ASTM Syntax
The structure of the sentences to be transferred is explained in this section according to
ASTM Communication Regulation. Between the analyzer and the host, various data such as
Test Orders and Results are transferred back and forth. All of these data conform to this
syntax.
This section deals with message coding rules as well as special characters, such as de-
limiters, used to develop messages provided by records and fields.
7.1.4.1 Definitions
Message
A message is constructed with an arrangement of several records (refer to the next
item). It is the smallest unit of information transferred between a host and an analyzer.
Messages begin with a ‘Message Header Record’ that indicates the beginning of a
message and end with a ‘Message Termination Record’ that indicates the end of a
message.
Record
A record is constructed from several fields and expresses a single purpose (such as to
specify result reports or test requests). A record may be repeated or used singularly in a
message. Code that indicates the purpose of a record, is noted in the first character of
that record.
Field
A field is the ASTM’s smallest element to construct information. Attributes for a field
(name, format, and meanings) are defined as units in a record.
7.1.4.2 Messages
Each message has a number of records. A message is a group of records that begins with a
Header Record and ends with a Message Terminator Record. Each record has a number of
fields. Each field is by default separated by the vertical bar | character (the actual definition
of which character is used for field separation is done with the Header Record).
Following is a description of the records and the fields within each record:
ID Record Types
H Header Record
L Message Termination Record
P Patient Record
O Test Order Record
R Result Record
C Comment Record
Q Request Record
M-X Manufacturer specific records
Note: The record type ID is not case sensitive; however, it is suggested to always use uppercase
characters.
