INV-1: Substance Identifier (CWE) 01372

Definition: Unique identifier for the substance that is in inventory. This is a manufacturer-specific identifier. Refer to User-defined Table 0451 – Substance Identifier in Chapter 2C, Code Tables, for suggested values.

This field is conditional. It is optional in queries INR^U14 and required in all other messages. Absence of this field in a query means that the result shall be not filtered on inventory item ID.

INV-2: Substance Status (CWE) 01373

Definition: The status of the inventoried item. The status indicates the current status of the substance. Refer to HL7 Table 0383 – Substance Status in Chapter 2C, Code Tables, for suggested values.

This field is conditional. It is optional in queries INR^U14 and required in all other messages. Absence of this field in a query means that the result shall be not filtered on inventory item status.

INV-3: Substance Type (CWE) 01374

Definition: The type of substance. Refer to HL7 Table 0384 – Substance Type in chapter 2C for suggested values.

INV-4: Inventory Container Identifier (CWE) 01532

Definition: Identifies the inventory container, e.g., unique identifier of a specific package instance of a specific substance. This is a manufacturer-specific identifier.Refer to Table 0599 - Inventory Container Identifier in Chapter 2C for valid values.

INV-5: Container Carrier Identifier (CWE) 01376

Definition: This is the carrier used to transport the substance containers (e.g., a removable rotor with reagent bottles). Refer to Table 0600 - Container Carrier Identifier in Chapter 2C for valid values.

INV-6: Position on Carrier (CWE) 01377

Definition: Identifies the position (e.g., index) on the carrier. Refer to Table 0601 - Position on Carrier in Chapter 2C for valid values.

INV-7: Initial Quantity (NM) 01378

Definition: This field identifies the initial quantity of the substance in inventory.

INV-8: Current Quantity (NM) 01379

Definition: This field is the current quantity, i.e., initial quantity minus what has been actually used.

INV-9: Available Quantity (NM) 01380

Definition: This field is the available quantity of substance. This is the current quantity minus any planned consumption (e.g., tests that are planned).

INV-10: Consumption Quantity (NM) 01381

Definition: This field is the consumption that is used each time the equipment uses this substance.

INV-11: Quantity Units (CWE) 01382

Definition: This field is the units of measure of the available quantity. If the units are ISO+ units, they should be recorded as single case abbreviations. If the units are ANS+ or L (local), the units and the source code table must be recorded, except that in this case, component delimiters should be replaced by sub-component delimiters. For example, "l" indicates liters, whereas pt&&ANS+ indicates pints (ANSI units). The default unit is milliliters (ml), which should be assumed if no units are reported. Refer to Table 0602 - Quantity Units in Chapter 2C for valid values.

INV-12: Expiration Date/Time (DTM) 01383

Definition: This field is the expiration date/time of the substance.

INV-13: First Used Date/Time (DTM) 01384

Definition: This field is the time and date when the substance was first used. This date and time can be necessary to determine the stability of the substance. The meaning of the "first used" element depends on the substance. In certain cases it means the time when the substance was put on board of the instrument or prepared (mixed), without actually using it in the analysis.

INV-14: On Board Stability Duration () 01385

Attention: As of v2.5 this field was retained for backward compatibility only and withdrawn and removed as of v2.7. The TQ data type was deprecated; see Chapter 2A, section 2.A.81.

INV-15: Test/Fluid Identifier(s) (CWE) 01386

Definition: This field is the list of tests and body fluids that relate or correspond to this inventory item . This is a repeating field. An empty field means that this inventory item is not test specific, i.e., it applies to all tests. Refer to Table 0603 - Test/Fluid Identifier(s) in Chapter 2C for valid values.

INV-16: Manufacturer Lot Number (ST) 01387

Definition: This field specifies the lot number assigned by the manufacturer during production of the substance.

INV-17: Manufacturer Identifier (CWE) 00286

Definition: This field identifies the manufacturer of this substance. Refer to User-defined Table 0385 – Manufacturer Identifier in Chapter 2C, Code Tables, for suggested values. Relevant external code systems may be used, e.g., HIBCC Manufacturers Labeler ID Code (LIC), UPC, NDC, etc.

INV-18: Supplier Identifier (CWE) 01389

Definition: This field identifies the supplier of this substance. Refer to User-defined Table 0386 – Supplier Identifier in Chapter 2C, Code Tables, for suggested values.

INV-19: On Board Stability Time (CQ) 01626

Definition: This field is the duration of time that the calibration/usability of the substance is stable. The duration is used to calculate the date/time when this calibration is no longer valid by adding this "On board stability time" (INV-19) to the "First used date / time" (INV-13).

The 1st component defines the time quantity and the 2nd component the time units (see HL7 Table 0255 – Duration Categories). Recommended accuracy is "minutes", "hours" and "days".

INV-20: Target Value (CQ) 01896

Definition: This field is the target analytical value for a particular test for a specific lot of a manufactured material. Target values for QC purposes are usually selected for their relevance to a reference (normal) range or to a clinically significant decision level.

The 1st component defines the value and the 2nd component the measurement units.

INV-21: Equipment State Indicator Type Code (CWE) 03488

<Alternate Identifier (ST)> ^ <Alternate Text (ST)> ^ <Name of Alternate Coding System (ID)> ^ <Coding System Version ID (ST)> ^ <Alternate Coding System Version ID (ST)> ^ <Original Text (ST)> ^ <Second Alternate Identifier (ST)> ^ <Second Alternate Text (ST)> ^ <Name of Second Alternate Coding System (ID)> ^ <Second Alternate Coding System Version ID (ST)> ^ <Coding System OID (ST)> ^ <Value Set OID (ST)> ^ <Value Set Version ID (DTM)> ^ <Alternate Coding System OID (ST)> ^ <Alternate Value Set OID (ST)> ^ <Alternate Value Set Version ID (DTM)> ^ <Second Alternate Coding System OID (ST)> ^ <Second Alternate Value Set OID (ST)> ^ <Second Alternate Value Set Version ID (DTM)>

Definition: The type code of an equipment state indicator. Refer to HL7 Table 0942 – Equipment State Indicator Type Code in Chapter 2C, Code Tables, for suggested values.

Due to its dynamic nature, an equipment state indicator is considered to be a [non-material] inventory item. Its value usually can be derived from the material inventory — in that way, a state indicator differs from static configuration parameters and master data stored on the equipment.

This field is conditional. It is optional when INV-3 “Substance Type” is not populated and prohibited otherwise.

INV-22: Equipment State Indicator Value (CQ) 03489

Definition: The numeric value of the equipment state indicator specified in INV-21. The 1st component defines the number and the 2nd component the units of measurement.

This field is conditional. It is optional when INV-21 “Equipment State Indicator Type Code” is populated and prohibited otherwise.
