Although the Freedom Lite is an Abbott meter, it is calibrated for Plasma, so should be the same as the Codefree in that respect. Other Abbott meters that I have seen appear to be whole blood instead.
Cannot find any definition for the Libre, but a 48 day trial comparing it to a Dexcom G4 showed it was about 12% out when the Dexcom showed a hypo event, The difference between the two meters had a worst case discrepancy of some 20% on occasions. This info seems to imply that the plasma vs Whole blood effect is happening but which is which way it goes is not apparent from the limited info in the report. The Libre manuals just say it is 'factory calibrated'
Edit to add: The Dexcom must be calibrated against a standard glucometerr that is to hand, so will inherit the scaling of the meter being used plus any reading error. So it is dependant on the meter used. In the review I used above, this other meter was not identified, so all we can say is one was probably plasma, and the other whole blood.
