This is an example of how the Specimen Module can be populated for a slide (from a lung lobe resection received from surgery). The associated image would be a whole slide image.
Table NN.6-3. Specimen Module for a Slide
|
The identifier for the container that contains the specimen(s) being imaged. |
||||
|
Type of container that contains the specimen(s) being imaged. Only a single item shall be permitted in this sequence |
This would likely be a default container value for all slide specimens. |
|||
|
Description of one or more components of the container (e.g., description of the slide and of the coverslip). One or more Items may be included in this Sequence. |
||||
|
Type of container component. One Item shall be included in this Sequence. |
||||
|
Sequence of identifiers and detailed description of the specimen(s) being imaged. One or more Items shall be included in this Sequence. |
||||
|
A departmental information system identifier for the Specimen. |
||||
|
The name or code for the institution that has assigned the Specimen Identifier. |
||||
|
This Attribute concatenates four LIS fields: 1. Specimen Received, 2. Cassette Summary, 3. Number of Pieces in Block, 4. Staining. This does not always work this nicely. Often one or more of fields is empty or confusing. |

A: Received fresh for intraoperative consultation, labeled with the patient's name, number and "left upper lobe," is a pink-tan, wedge-shaped segment of soft tissue, 6.9 x 4.2 x 1.0 cm. The pleural surface is pink-tan and glistening with a stapled line measuring 12.0 cm. in length. The pleural surface shows a 0.5 cm. area of puckering. The pleural surface is inked black. The cut surface reveals a 1.2 x 1.1 cm, white-gray, irregular mass abutting the pleural surface and deep to the puckered area. The remainder of the cut surface is red-brown and congested. No other lesions are identified. Representative sections are submitted. |
This is a mapping from the LIS Gross Description Field and the Block Summary. Note that in Case S07-100, there were six parts. This means the LIS gross description field will have six sections (A - F). We would have to parse the gross description field into those parts (A-F) and then only incorporate section "A" into this Attribute. The same would be true of the Blocks. |

|
Sequence of Items identifying the process steps used to prepare the specimen for image acquisition. One or more Items may be present. This Sequence includes description of the specimen sampling step from a parent specimen, potentially back to the original part collection. |
(see Table NN.6-4) |
|||
|
Sequence of Content Items identifying the processes used in one preparation step to prepare the specimen for image acquisition. One or more Items may be present. |
||||
|
Original anatomic location in patient of specimen. This location may be inherited from the parent specimen, or further refined by modifiers depending on the sampling procedure for this specimen. |
||||
The example Specimen Preparation Sequence first describes the most recent processing of the slide (staining), then goes back to show its provenance. Notice that there is no sampling process for the slide described here; the LIS did not record the step of slicing of blocks into slides.
