In many laboratory studies such as medicine, fisheries, and chemistry comparison of two different methods of measurement is of great importance. These measurements are critical when the methods are changed, a new or alternative method proposed, or two exciting methods are not in complete agreement. The most common used methods such paired t-test, correlation and regression can be misleading, thus, Altman and Bland introduced a new method to address the shortages of those methods. However, Altman-Bland method is not introducing a test of significance. Moreover, threshold and intervals in this method are not set in prior. These two drawbacks are addressed in this study. P-value quantified for the Altman-Bland method and thresholds are set before the run of test.
