Folic acid deficiency anemia

Red Cell Distribution Width (Standard Deviation) is another measure of red blood cell size variation using standard deviation. It provides similar information to RDW-CV but with a different calculation method.

Red Cell Distribution Width (Coefficient of Variation) measures the variation in red blood cell size. Elevated values indicate greater variation in cell size (anisocytosis) and can help diagnose certain anemias.

Mean Corpuscular Volume measures the average size of red blood cells. It helps diagnose different types of anemia - elevated in macrocytic anemia, decreased in microcytic anemia, and normal in normocytic anemia.

Mean Corpuscular Hemoglobin Concentration measures the average concentration of hemoglobin in a given volume of red blood cells. It helps distinguish between different types of anemia and assess cell hydration status.

Mean Corpuscular Hemoglobin measures the average amount of hemoglobin per red blood cell. It helps evaluate the hemoglobin content of cells and is used alongside other RBC indices to classify anemias.

Hemoglobin is a protein in red blood cells that binds to oxygen in the lungs and delivers it to tissues throughout the body. It also plays a role in transporting carbon dioxide back to the lungs for exhalation.

Hematocrit measures the percentage of blood volume occupied by cellular components, with the largest portion being red blood cells (erythrocytes). When blood is centrifuged, blood cells settle at the bottom, creating a visible layer that indicates their proportion relative to total blood volume.

Vitamin B12 is a water-soluble vitamin essential for the production of red blood cells, the synthesis of DNA, and the healthy functioning of the nervous system. It also supports brain function and energy metabolism. The body cannot make B12 on its own and relies on dietary sources such as meat, fish, eggs, and dairy. Excess B12 is stored in the liver, so deficiency can take time to develop but may lead to serious health issues if not addressed.

Folic acid, or folate in its natural form, is a water-soluble B vitamin that plays a key role in cell division, DNA synthesis, and red blood cell formation. It is especially important during periods of rapid growth, such as pregnancy and adolescence. Folate is found in leafy greens, legumes, citrus fruits, and fortified foods. The body cannot produce folate and depends on regular dietary intake.
