Which would you expect to see on a blood smear for megaloblastic anemia?
A peripheral blood smear may reveal macro-ovalocytes, anisocytosis, poikilocytosis, and hypersegmented neutrophils, a specific indicator of megaloblastic anemia.

What is the peripheral blood in megaloblastic anemia?
Peripheral Blood Smear The presence of macro-ovalocytes having an MCV >115 fl, anisocytosis, poikilocytosis and hypersegmented neutrophils suggests a megaloblastic disorder associated with a nutritional deficiency, i.e., vitamin B12 or folate deficiency.
What is peripheral smear in blood test?
A peripheral blood smear test shows how your blood cells and platelets look under a microscope. Looking through a microscope, your healthcare provider may see: Changes in your blood cell and platelet size and shape may be a sign of a blood disorder or blood cancer.
How do you diagnose megaloblastic anemia?
A diagnosis of megaloblastic anemia is made based upon a thorough clinical evaluation, a detailed patient history, identification of characteristic findings and a variety of blood tests. Blood tests may reveal the abnormally large, misshapen red blood cells that characterize megaloblastic anemia.
Can you cure megaloblastic anemia?
The treatment of megaloblastic anemia depends upon the underlying cause of the disorder. Dietary insufficiency of cobalamin and folate can be treated with appropriate changes to the diet and the administration of supplements.
Why is folic acid useful in the treatment of megaloblastic anemia?
Folic acid is a B vitamin that helps your body make red blood cells. If you don’t have enough red blood cells, you have anemia. Red blood cells carry oxygen to all parts of your body. When you have anemia, your blood can’t bring enough oxygen to all your tissues and organs.
What is the expected finding in the peripheral blood smear of the patient and how it will cause anemia?
Peripheral Smear Examination of the erythrocytes shows microcytic and hypochromic red blood cells in chronic iron deficiency anemia. The microcytosis is apparent in the smear long before the MCV is decreased after an event producing iron deficiency. Platelets usually are increased in this disorder.
Why is peripheral smear test done?
A peripheral blood smear test is a technique healthcare providers use to examine your red and white blood cells and your platelets. This test gives them a clear picture of changes in your blood cells and platelets that may be a sign of disease. A peripheral blood smear test is an important part of diagnosing disease.
What are the importance of peripheral blood smear in diagnosing a certain disease?
The test provides information on the number and shape of these cells, which can help doctors diagnose certain blood disorders or other medical conditions. Irregularities in the number or shape of your red blood cells can affect how oxygen travels in your blood.
Why MCHC is normal in megaloblastic anemia?
Defects in nuclear maturation, as seen in megaloblastic anemias due to folate or B12 deficiency, result in large oval erythrocytes (macroovalocytes) with a normal hemoglobin content. The MCV and MCH are increased, while the MCHC remains normal.
How long does it take to recover from megaloblastic anemia?
While most mild neurologic abnormalities that may have arisen in the past 3 months can be expected to improve in up to 90% of patients within about 6 months, those with more prolonged symptoms could take a year to recover completely.
How do you treat high folate levels?
Excess folic acid is excreted in urine. A high folate intake can mask vitamin B-12 deficiency until its neurological effects become irreversible. This can typically be remedied by taking a supplement containing 100 percent of the daily value of both folic acid and vitamin B-12.
Does folate increase hemoglobin?
Conclusion: Supplementation of folic acid and/or vitamin B12 for 6 months does not improve Hb concentration in young children. Our findings do not argue for widespread vitamin B12 or folic acid supplementation to combat anemia.
How is hemolytic anemia treated?
Treatments for hemolytic anemia include blood transfusions, medicines, plasmapheresis (PLAZ-meh-feh-RE-sis), surgery, blood and marrow stem cell transplants, and lifestyle changes. People who have mild hemolytic anemia may not need treatment, as long as the condition doesn’t worsen.
What does a peripheral smear show?
What is a peripheral smear?
A procedure in which a sample of blood is viewed under a microscope to count different circulating blood cells (red blood cells, white blood cells, platelets, etc.) and see whether the cells look normal.
