What is the morphology of microcytic anemia?
In classic cases, the morphological differentiation of the three common microcytic anemias is straightforward. The classic morphology in ACD is of unremarkable RBCs, while iron deficiency shows anisocytosis, anisochromia, and elliptocytosis, and thalassemia trait demonstrates target cells and coarse basophilic stippling.
Why is my RBC count low?
low counts due to faulty aspiration of whole blood by the automated counter; macrocytosis due to RBC agglutination or rouleaux, hyperleukocytosis, or severe hyperglycemia; microcytosis due to the blood counter's misidentification of giant platelets as RBCs.

For laboratory hematology professionals, the complete blood count (CBC) and the peripheral smear are, respectively, our history and physical examination. Despite quantum leaps in technological development in the clinical laboratory, with evolutions and revolutions in flow cytometry and point of care testing and molecular analysis, review of a patient's CBC and peripheral smear morphology is still the mainstay of hematologic diagnosis.
Is the zone of central pallor linear or circular?
The zone of central pallor is linear , rather than circular. Usually the ‘line of pallor’ runs parallel to the long axis of the RBC, if the latter is ovoid, but in certain variants (e.g., South East Asian ovalocytosis), the line may run across the long axis or may be nonlinear, for example, bifurcated or trifurcated.

What are the conditions that affect RBC morphology?
However, the Medical College of Virginia explains that abnormalities in RBC morphology are associated with a number of conditions, including sickle cell anemia, thalassemia, heavy metal poisoning, tuberculosis, uremia and others. The treatment for each depends on the condition or disease.
What is the disease that causes red blood cells to die?
One of the more common of these is sickle cell anemia, a disease in which hemoglobin, a protein found in red blood cells, is abnormal and causes the cells to assume a sickle shape. These cells die more quickly than normal cells, causing chronic anemia.

The RBC indices can help your doctor determine the cause if your doctor thinks you have anemia. The MCV is the most useful value in the RBC indices to help determine the type of anemia you may have.
What is the blood that carries oxygen?
Blood consists of RBCs, white blood cells (WBCs), and platelets that are suspended in your plasma. Platelets are cells that enable clot formation. RBCs contain hemoglobin, which carries oxygen throughout your body to all of your tissues and organs. An RBC is pale red and gets its color from hemoglobin. It’s shaped like a doughnut, but it has a thinner area in the middle instead of a hole. Your RBCs are normally all the same color, size, and shape. However, certain conditions can cause variations that impair their ability to function properly.
How do you know if you have anemia?
The CBC is a broad test that measures the number of all RBCs, WBCs, and platelets in a sample of blood. If you’re found to have anemia, the RBC and the RBC indices can help to determine what’s causing your anemia.
What is the RBC test used for?
Your RBC indices and RBC count are used to diagnose different types of anemia. You have some form of anemia if you have a low RBC count or abnormal RBC indices.
What is the purpose of RBC indices?
The RBC indices measure the size, shape, and physical characteristics of the RBCs. Your doctor can use RBC indices to help diagnose the cause of anemia. Anemia is a common blood disorder in which you have too few, misshapen, or poorly functional RBCs.
What does MCHC mean?
mean corpuscular hemoglobin concentration (MCHC), which is the amount of hemoglobin relative to the size of the cell or hemoglobin concentration per red blood cell
Why is my MCV lower than normal?
The MCV will be lower than normal when red blood cells are too small. This condition is called microcytic anemia.
