Yes, a repeat blood count is necessary. However—and this is important—you really need to insist that they test the platelets in a citrate solution.
There is a condition known as pseudothrombocytopenia (false thrombocytopenia). Essentially, in certain individuals (which isn't all that rare), the blood reacts with the EDTA acid used in the collection tube. This causes the platelets to clump together, which results in a falsely low TRC reading—even though the actual number and function of the platelets are perfectly normal.
Furthermore, while we are looking at a mild normocytic anemia—and considering the patient's thin build—I would recommend some additional testing (at minimum Fe, UIBC, TIBC, and ferritin), and if possible, an expanded metabolic panel. This is primarily to determine if there is an underlying iron deficiency and to assess how the other organs are functioning.
It simply doesn't make sense to jump to conclusions before these additional tests are completed.
