Germany is not that much different. The lab will provide barcodes to the 
praxis. Someone draws the blood and pots a barcode on the tube. It is up to 
the praxis to manually associate the barcode with a patient. The lab will only 
return results and the barcode as idetifier. They don't know the patient name.
