Nature of Service/Test/Observation
2000-10-28
Definition: This field indicates whether the definition entry identifies a test battery, an entire functional procedure or study, a single test value (observation), multiple test batteries or functional procedures as an orderable unit (profile), or a single test value (observation) calculated from other independent observations. Refer to User-defined Table 0174 - Nature of service/test/observation for suggested values.

5 values
A | Atomic service/test/observation (test code or treatment code) |
C | Single observation calculated via a rule or formula from other independent observations (e.g., Alveolar--arterial ratio, cardiac output) |
F | Functional procedure that may consist of one or more interrelated measures (e.g., glucose tolerance test, creatinine clearance), usually done at different times and/or on different specimens |
P | Profile or battery consisting of many independent atomic observations (e.g., SMA12, electrolytes), usually done at one instrument on one specimen |
S | Superset--a set of batteries or procedures ordered under a single code unit but processed as separate batteries (e.g., routines = CBC, UA, electrolytes); This set indicates that the code being described is used to order multiple service/test/observation b |
