In brief: Many answers

One would want the hemoglobin and hematocrit levels to more accurately answer your question.
The MCV above is borderline low based on a usual normal range that starts about 80. Low iron levels are the most common cause for a low mcv. I would have the complete blood count repeated before being overly worried about the above listed values.
