Anemia is a condition marked by a decrease in the number of red blood cells (rbc), the proportion of hemoglobin, or the collective volume of packed rbcs (hematocrit). the main function of rbcs, or erythrocytes, is to carry oxygen from the lungs to the body tissues and carbon dioxide as a waste product from the body tissues to the lungs back. this process is facilitated by hemoglobin (hb). a. The presence of hematuria is most important to confirm, since both normal and abnormal causes (eg, hemoglobinuria, myoglobinuria) can produce false-positive results. confirmation requires a microscopic examination of the urine for the presence of rbcs and casts. a freshly voided urine specimen should be used.. A type of anemia (low red blood cell count) caused by the body’s inability to absorb vitamin b12. definition (nci) megaloblastic anemia caused by vitamin b-12 deficiency due to impaired absorption. the impaired absorption of vitamin b-12 is secondary to atrophic gastritis and loss of gastric parietal cells. definition (msh).

Anemia in children is commonly encountered by the family physician. multiple causes exist, but with a thorough history, a physical examination and limited laboratory evaluation a specific. Ajay k. singh, in textbook of nephro-endocrinology (second edition), 2018 abstract. normal erythropoiesis results in the generation of sufficient numbers of fully functional mature red blood cells to replace senescent ones. to achieve this goal, a host of growth factors and the element iron are necessary ingredients that are used by erythroid precursor cells for effective erythropoiesis..
Elliptocytes: the rbcs are ovaal or elliptical in shape, long axis is twice the short axis.. elliptocytes are found in : hereditary elliptocytosis, megaloblastic anemia, ida, thalassemia, myelofibrosis. target cells: red cells have an area of increased staining which appears in the area of central pallor. target cells are found in : obstructive liver disease, severe ida, thalassemia. Anemia in children is commonly encountered by the family physician. multiple causes exist, but with a thorough history, a physical examination and limited laboratory evaluation a specific. Anemia or anaemia (british english) is a blood disorder in which the blood has a reduced ability to carry oxygen due to a lower than normal number of red blood cells, or a reduction in the amount of hemoglobin. when anemia comes on slowly, the symptoms are often vague, such as tiredness, weakness, shortness of breath, headaches, and a reduced ability to exercise..
Having a nucleus (nucleated red blood cell, not normal in a mature rbc) or crystal (e.g., c crystal) having uneven hemoglobin distribution (producing “ target cells ” that look like a bull’s-eye under the microscope). the greater the percentage of abnormal-looking red blood cells, the greater the likelihood of an underlying disorder.. Abnormal skeletal muscle morphology: hp:0003735: a structural abnormality of a skeletal muscle. abnormal muscle morphology; abnormality of muscle morphology; abnormally shaped muscle; issue with muscle structure: hp:0011842: abnormal skeletal morphology: an abnormality of the form, structure, or size of the skeletal system..
