Notes:
In addition to the LNC SAB, LOINC includes 15 subsources, which
are assigned by an algorithm using field 34
(EXTERNAL_COPYRIGHT_NOTICE), field 8 (CLASS) and field 7
(METHOD_TYP). The representation described below apply to elements
from all subsources. Due to licensing restrictions, concepts from
the following subsources are not included in Metathesaurus processing:
- Ages & Stages Questionnaire
- Edinburgh Postnatal Depression Scale
- TIMP (Test of Infant Motor Performance)
- PROMIS (Patient Reported Outcomes Measurement System survey)
- Veterans RAND 12 Item Health Survey

Original Files:
The UMLS uses files publically available at www.loinc.org, including: "LOINCDB.TXT" (compressed in "LOINC240.zip") and "LOINC_V240_MULTI-AXIAL_HIERARCHY.CSV" (compressed in "LOINC_V240_MULTI-AXIAL_HIERARCHY.ZIP"). In addition, the UMLS receives two files to facilitate building the hierarchy. For 2.40, these files were: "LOINC_PART_LINKS_V2-40_2012-06-28.txt" and "LOINC_PARTS_V2-40_2012-06-28.txt". Additional information, such as expansions of abbreviations, is extracted from LOINCManual.pdf.
Overview
Identifiers
LOINC Identifiers in the UMLS are generally based on field 1 of LOINCDB.TXT (LOINC_NUM), or field 1 of LOINC_PARTS (L_PART_ID). For some termtypes, the atom may be associated with multiple LOINC entities. For example, a component may be a part of multiple fully-specified names. In these cases, the atom (e.g. a CN, or Official Component Name), is assigned an MTHU# during Metathesaurus source processing.
- CODE:
- For term types LC, LN, LO, MTH_LN, MTH_LO, OLC, OOSN, OSN: the LOINC _NUM (field 1) from LOINCDB.TXT
- For term types LPDN, LPN: the L_PART_ID (field 1) from LOINC_PARTS_*.txt
- For term types CN, MTH_CN, HC, HS, LS: an MTHU#, assigned during Metathesaurus source processing.
- SAUI: Not Applicable
- SCUI: Same as CODE for term types LC, LN, LO, LPDN, LPN,
MTH_LN, MTH_LO, OLC, OOSN, OSN
- SDUI: Not Applicable
Expansions
Expanded forms of certain atoms are created during Metathesaurus source processing by applying abbreviation expansions extracted from the LOINC Manual. In these cases, the expanded form is generally assigned the same identifier as its original form. Expansions may also include converting patterns such as "little e" or “super little b" to “e" or "^b" respectively.
Atoms
)| TTY | ORIGIN |
|---|---|
| CN | Official component name: CODE = MTHU#, assigned during Metathesaurus source processing; same as CODE for respective MTH_CN as applicable. STR = LOINCDB.TXT field 2, subfield 1 (COMPONENT). |
| HC | Hierarchical class: CODE = MTHU#, assigned during Metathesaurus source processing (same as CODE for respective HS). STR = expanded form of LOINCDB.TXT field 8 for CLASS or expanded form of LOINCDB.TXT field 17 for CLASSTYPE. An additional HC atom, “LOINCCLASSTYPES,” is added during Metathesaurus source processing as a hierarchical placeholder. |
| HS | Short or alternate version of hierarchical term: CODE = MTHU#, assigned during Metathesaurus source processing (same as CODE for respective HC). STR = value of LOINCDB.TXT field 8 for CLASS, or value of LOINCDB.TXT field 17 for CLASSTYPE. |

| LPDN | Parts display name: CODE = LOINC_PARTS_*.txt field 1 (L_PART_ID) STR = LOINC_PARTS_*.txt field 4 (DISPLAY_NAME) LPDN atoms are only created for strings containing the pattern “Allergen Mix.” |

| MTH_LO | Expanded obsolete fully specified name: CODE = LOINCDB.TXT field 1 (LOINC_NUM) STR = Expanded form of LOINCDB.TXT fields 2-7, concatenated with colons, i.e. F2:F3:F4:F5:F6:F7 TTY = MTH_LO is assigned if field 13 = "DEPRECATED" SUPPRESS = O |

| OLC | Obsolete long common name: CODE = LOINCDB.TXT field 1 (LOINC_NUM) STR = LOINCDB.TXT field 36 (LONG_COMMON_NAME) TTY = OLC is assigned if field 13 = "DEPRECATED" SUPPRESS = O |
| OOSN | Obsolete official short name: CODE = LOINCDB.TXT field 1 (LOINC_NUM) STR = LOINCDB.TXT field 30 (SHORTNAME) TTY = OOSN is assigned if field 13 = "DEPRECATED" SUPPRESS = "O" |
| OSN | Official short name: CODE = LOINCDB.TXT field 1 (LOINC_NUM) STR = LOINCDB.TXT field 30 (SHORTNAME) TTY OSN is assigned if field 13 is not = “DEPRECATED” |
