ABSTRACT:
A method for determining the value of MCV of a fresh sample of blood when the value of MCV for that sample of blood is known, but the period of time that the sample of blood has been stored is not known. The method of this invention allows an automated hematology analyzer to provide a more reliable indication of the initial value of MCV of a sample of blood, i.e., the value of MCV that would have been expected for the sample of blood when the sample was fresh. Furthermore, the method of this invention uses data that is readily available as part of the blood count data.
