Specimen Type Modifier

The use of this attribute is to modify, qualify or further specify, the entity described by SPM-4 -Specimen Type. This is particularly useful when the code set used in SPM-4-Specimen Type does not provide the precision required to fully describe the specimen. For example, if the specimen was precisely described as _capillary venous blood_ but the code set employed only provided _venous blood,_ this attribute could be employed to add the modifier _capillary._
