What do these results mean? Decreased MCH and elevated RDW in blood test?

Suggests low iron. Mean corpuscular hemoglobin (mch) relates to how much hemoglobin on your red blood cell (see mchc - adds concentration to mch). Forget exact acronym, but RDW measures (via flow cytometry) size of many red cells--normal to have all about one size. If becoming anemic, see wide variation which raises RDW #. Both of these can be due to low iron, but also folate (folic acid) or B12--ask your Dr for context & plan.
