He reported eating a balanced diet of fruits, vegetables, meat, and dairy products. Physical examination, he appeared slightly pale but had no other abnormalities. His laboratory results was a following: Hemoglobin Hematocrit 12.5 g/dL 32% 4.2 X 1012/L RBC WBC count within normal limits 42 fL MCV МСН 29.7 pg Urinalysis is normal Fecal occult blood found to be positive 1- What is the most likely cause of this patient's anemia? 2- What type of red cell morphology would be expected on a peripheral blood smear? 3- What follow-up tests should be conducted? 4- What do you expected the treatment for this patient would be? 5- What would you expected about the reticulocyte count to be for this patient? (Increase/ decrease/ normal)? Why?
