In brief: Making new blood

A high RDW means that there is a mixture of red blood cells of different sizes.
Young cells are larger than old ones. Iron deficiency causes smaller cells, vitamin deficiency larger ones. If everything else is okay, it is probably not a problem. The doctor who ordered the test and knows her can say more.
