he following article examines options for evaluating precision for test methods in
AOAC’s standards development processes. It reviews the use of proficiency testing
data, intermediate reproducibility, and measurement uncertainty as alternative
procedures to performing a collaborative study. For more information on estimating
method reproducibility, or other related questions in evaluating method performance,
