Template  SPS - Specimen source

Contains the specimen source name or code (as a CWE data type component). (Even in the case of observations whose name implies the source, a source may be required, e.g., blood culture-heart blood.)

A nationally recognized coding system is to be used for this field. Valid coding sources for this field include:

• HL7 table 0487 – Specimen Type (replaces HL7 table 0070 – Specimen source codes)
• SNOMED, etc.
• Veterinary medicine may choose the tables supported for the components of this field as decided by their industry.

Identifies an additive introduced to the specimen before or at the time of collection. Refer to HL7 Table 0371 – Additive in chapter 7 for valid values. The table’s values are taken from NCCLS AUTO4. The value set can be extended with user specific values.

Describes the method of collection when that information is a part of the order. When the method of collection is logically an observation result, it should be included as a result segment (i.e., OBX segment).

This component specifies the body site from which the specimen was obtained. A nationally recognized coding system is to be used for this field. Valid coding sources for this field include:

• HL7 Table 0163 - Body site
• SNOMED

Modifies body site. For example, the site could be antecubital fossa, and the site modifier "right." Refer to HL7 Table 0495 Body Site Modifier for allowed values.

Indicates whether the specimen is frozen as part of the collection method. Suggested values are F (Frozen); R (Refrigerated). If the component is blank, the specimen is assumed to be at room temperature.

Indicates the role of the sample. Refer to User-defined Table 0369 – Specimen role for suggested values. Each of these values is normally identifiable by the systems and its components and can influence processing and data management related to the specimen.
