I added:

	In the case of a blood pressure measurement, the specimen invariably  
the patient!

I added

	It would be possible to use different test types to distinguish  
blood pressure measurements as recorded manually in-office by a  
clinician from those done by an automated or ambulatory device.

Conjecture: whether to unify all types of blood pressure readings  
could be decided at a praxis level. It could be decided to unify in- 
office readings (whether done by the clinician or by a machine) and  
to separately unify automated ambulatory and patient self- 
measurement, but to avoid unifying across all of these, since in- 
office and ambulatory are held to have different meanings.
