Consensus error grid

The consensus error grid (also known as the Parkes error grid) was developed as a new tool for evaluating the accuracy of a blood glucose meter. In recent times, the consensus error grid has been used increasingly by blood glucose meter manufacturers in their clinical studies. It was published in August 2000 by Joan L. Parkes, Stephen L. Slatin, Scott Pardo, and Barry H. Ginsberg.

Consensus error grid in clinical studies

Please note: The bias error is NOT EQUAL the precision of the glucose test result.

Compare the Clarke Error Grid Zone A which considers 20% error as tolerable.
