8.5 “X-B Analysis” Program
The X-B
analysis is a weighted moving average analysis that uses values obtained from
patient samples. It was proposed by Brian Bull, M.D. using the 3 red cell indices, MCV, MCH
and MCHC to indicate the hematology instrument performance. Effective use of X-B requires
randomization of samples and a normal cross section of patients to prevent skewing of
indices.
It is recommended the X-B analysis be enabled when the sample volume of your laboratory is
greater then 100 samples per day.
