Understanding Abnormal Blood Test Results: RBC, RDW, MCV, MCH, and ESR

Question
Hello - I am struggling to find answers to my latest test results.
RBD - L 6.68 / RDW - L 11.0
MCV - H 102 / MCH - H 35.9 / Sed rate - H 21.0
My HGB (13.2), HCT (37.7), MCHC (35.0), Platelets (315) are all within normal rates. My Folate (11.7) , and Vitamin B-12 (549) seem to be in order, as well.
Any ideas?  I'm set for a retest in 30 days.

Answer
Hi Barbara.  Have you spoken to your doctor?  Did he/she mention why you're to have a retest?  It appears to me that all of the results you've listed are only slightly out of normal range.  These slight variations are unlikely to be of any clinical significance.
