What is common between intra-assay, intermediate, and interlaboratory precision?

All three terms refer to measures of the precision or repeatability of a laboratory test or assay. They all assess the consistency of results obtained from the same sample or samples under different conditions, such as within the same assay, between different runs within the same laboratory, or between different laboratories. These measures are important for evaluating the reliability and accuracy of a test or assay.

All of them are measures of analytical method variability.
