Cbc done - hgb, hct low (10.6/33.3). The mcv, MCH and MCH were borderline low. The RDW high. Donated blood 1 month previous with 12.9 hgb.? Diagnosis

Not enough data. Most cbc's only tell us what numerically is wrong. The only sure way to tell a CBC is abnormal is to look at the peripheral smear. Your indices indicate that you may be iron deficient, however that requires a thorough assessment for blood loss from the gi, gu and respiratory tract. If you donate blood, you can exacerbate the iron deficiency.
