A patient's red cell indices can be used in discriminant functions to aid in the diagnosis of microcytic anemia.
Red cell indices used:
(1) MCH in picograms
(2) MCV in femtoliters
(3) RBC count as 10^12/L
(4) RDW in percent
group classification function =
= ((coefficient for MCH) * (MCH in picograms)) + ((coefficient for MCV) * (MCV in femtoliters)) + ((coefficient for RBC) * (RBC in 10^12/L)) + ((coefficient for RDW) * (RDW in percent)) + (constant)
• The group with the highest classification function result is the probable diagnosis.
NOTE: When the data on page 681 is entered into the equations, my results are about 55-57 points lower than that given in the paper (260.72 vs 315.003, etc.)
