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.'
