A 23-year-old woman is currently being treated for anemia by her doctor.
She had an appendectomy one week ago.
Her hemoglobin level was 13.4 g/dL before surgery.
Her lab results showed a 10.3 g/dL level today, and the doctor deduced that she lost a significant amount of blood during her appendectomy.
Prior to the surgery, she had no history of anemia.
What is the accurate anemia diagnosis for this patient?
