Large variations in the shapes of erythrocytes (red blood cells) is a condition called poikilocytosis, according to CellaVision. These shape variations, along with other symptoms, can indicate iron-deficiency anemia in humans. Patient.co.uk reveals that abnormal sizes in red blood cells may also indicate anemia.Know More
Poikilocytosis is a general term because clinicians must determine what causes the variations in shapes. MediaLab Incorporated states that accurate diagnosis of red blood cell morphology is possible through scanning electron microscope technology. Such scans greatly increased hematologists' understanding of abnormal red blood cells.
Confirming an anemia diagnosis may include detecting the presence of these abnormally shaped cells, measuring serum ferritin and checking hemoglobin levels in blood. Patient.co.uk indicates that iron-deficiency anemia can be solved by diet and iron supplements as prescribed by a doctor.
Examples of abnormally shaped red blood cells include spherocytes, stomatocytes, target cells, leptocytes, sickle cells, elliptocytes, acanthocytes and echinocytes. Each of these different shapes may indicate a different blood disorder. "Clinical Methods: The History, Physical, and Laboratory Examinations" reveals identifying these shapes is crucial to diagnosis of blood diseases and disorders.
Poikilocytosis can indicate liver disease in cats. Resources from the Cornell University College of Veterinary Medicine state that chemotherapy can cause abnormal shapes in blood cells. Poikilocytosis also points to problems in goats and other young ruminants.Learn more about Blood
The human body is capable of replacing the plasma from one pint of blood within 24 hours, while it takes four to six weeks for the body to completely replace the red blood cells from one pint of blood, according to the American Red Cross. For this reason, eight weeks is required between donations of blood to ensure the health and safety of the donor.Full Answer >
Blood of the AB type has both A antigens and B antigens carried on red blood cells but lacks both A and B antibodies in its plasma. These characteristics make the AB blood type the most restricted with regard to red cell transfusions but a universal donor for plasma transfusions.Full Answer >
The majority of the carbon dioxide transported through the human bloodstream is in the form of the bicarbonate anion (HCO3-), and it is carried within the red blood cells. A much smaller portion of the bicarbonate anion is carried by the blood plasma. Carbon dioxide in the form of bicarbonate can account for percentages as high as 70 to 90 percent of the blood's overall CO2 transport.Full Answer >
The major components of the blood are plasma, red blood cells, white blood cells and platelets. Plasma is a yellowish liquid that contains the other components of the blood as well as many different substances. These include proteins, such as albumin, globulin and fibrinogen.Full Answer >
