Properties
This code system defines the following properties for its concepts
| Name | Code | URI | Type | Description | 
| STATUS | STATUS | http://loinc.org/property/STATUS | string | Status of the term. Within LOINC, codes with STATUS=DEPRECATED are considered inactive. Current values: ACTIVE, TRIAL, DISCOURAGED, and DEPRECATED | 
| COMPONENT | COMPONENT | http://loinc.org/property/COMPONENT | Coding | First major axis-component or analyte: Analyte Name, Analyte sub-class, Challenge | 
| PROPERTY | PROPERTY | http://loinc.org/property/PROPERTY | Coding | Second major axis-property observed: Kind of Property (also called kind of quantity) | 
| TIME_ASPCT | TIME_ASPCT | http://loinc.org/property/TIME_ASPCT | Coding | Third major axis-timing of the measurement: Time Aspect (Point or moment in time vs. time interval) | 
| SYSTEM | SYSTEM | http://loinc.org/property/SYSTEM | Coding | Fourth major axis-type of specimen or system: System (Sample) Type | 
| SCALE_TYP | SCALE_TYP | http://loinc.org/property/SCALE_TYP | Coding | Fifth major axis-scale of measurement: Type of Scale | 
| METHOD_TYP | METHOD_TYP | http://loinc.org/property/METHOD_TYP | Coding | Sixth major axis-method of measurement: Type of Method | 
| CLASS | CLASS | http://loinc.org/property/CLASS | Coding | An arbitrary classification of terms for grouping related observations together | 
| VersionLastChanged | VersionLastChanged | http://loinc.org/property/VersionLastChanged | string | The LOINC version number in which the record has last changed. For new records, this field contains the same value as the VersionFirstReleased property. | 
| CLASSTYPE | CLASSTYPE | http://loinc.org/property/CLASSTYPE | string | 1=Laboratory class; 2=Clinical class; 3=Claims attachments; 4=Surveys | 
| ORDER_OBS | ORDER_OBS | http://loinc.org/property/ORDER_OBS | string | Provides users with an idea of the intended use of the term by categorizing it as an order only, observation only, or both | 
| HL7_ATTACHMENT_STRUCTURE | HL7_ATTACHMENT_STRUCTURE | http://loinc.org/property/HL7_ATTACHMENT_STRUCTURE | string | This property is populated in collaboration with the HL7 Payer-Provider Exchange (PIE) Work Group (previously called Attachments Work Group) as described in the HL7 Attachment Specification: Supplement to Consolidated CDA Templated Guide. | 
| VersionFirstReleased | VersionFirstReleased | http://loinc.org/property/VersionFirstReleased | string | This is the LOINC version number in which this LOINC term was first published. | 
| ValidHL7AttachmentRequest | ValidHL7AttachmentRequest | http://loinc.org/property/ValidHL7AttachmentRequest | string | A value of Y in this field indicates that this LOINC code can be sent by a payer as part of an HL7 Attachment request for additional information. | 
Filters
| Code | Description | Op | Value | 
| parent | Allows for the selection of a set of codes based on their appearance in the LOINC Multiaxial Hierarchy. Parent selects immediate parent only. For example, the code '79190-5' has the parent 'LP379670-5' | = | A Part code | 
| child | Allows for the selection of a set of codes based on their appearance in the LOINC Multiaxial Hierarchy. Child selects immediate children only. For example, the code 'LP379670-5' has the child '79190-5'. Only LOINC Parts have children; LOINC codes do not have any children because they are leaf nodes. | = | A comma separated list of Part or LOINC codes | 
| copyright | Allows for the inclusion or exclusion of LOINC codes that include 3rd party copyright notices. LOINC = only codes with a sole copyright by Regenstrief. 3rdParty = only codes with a 3rd party copyright in addition to the one from Regenstrief | = | LOINC | 3rdParty |
