red blood cell

n. Abbr. RBC
A cell in the blood of vertebrates that transports oxygen and carbon dioxide to and from the tissues. In mammals, the red blood cell is disk-shaped and biconcave, contains hemoglobin, and lacks a nucleus. Also called erythrocyte, red cell, red corpuscle.

red blood cell

(rĕd)
Any of the disc-shaped cells that circulate in the blood of vertebrate animals, contain hemoglobin, and give blood its red color. The hemoglobin binds to oxygen, which is then transported by the cells to all of the tissues of the body. The red blood cells of mammals have no nucleus. Red blood cells are formed in the bone marrow. Also called erythrocyte. See more at cell.
Did You Know? Blood contains many cell types, but the distinctive red color comes from the aptly named red blood cells (RBCs). RBCs have their rich red color because of a vitally important iron-containing protein called hemoglobin. The protein picks up oxygen molecules as the blood exchanges gases in the lungs. The RBCs then carry oxygen to the far reaches of the body, where it is released for use by other cells, such as those of the brain and muscles. Just as importantly, after the RBC drops off its load of oxygen, its hemoglobin picks up carbon dioxide, the waste product of those brain and muscle cells, and brings it back to the lungs to be breathed out. All animals have some oxygen distribution system, but only vertebrate animals use RBCs. In some invertebrate animals, such as the earthworm, oxygen is transported using hemoglobin that is freely dissolved in the blood. Other invertebrates don't use hemoglobin at all. The horseshoe crab, for instance, uses copper instead of iron, making its blood blue instead of red.

In fact, Samantaa et al., (2016) have reported effect of chronic fluorosis toxicity in blood cells of albino rats showed different types of abnormal erythrocytes, poikilocytes, and schistocytes.
Complete blood count revealed anemia (hemoglobin 9.9 g/dL), thrombocytopenia (platelet count 20,000) with microcytic hypochromic picture, and schistocytes on peripheral blood film.
Although the laboratory thresholds used to define HELLP syndrome are not unanimous, Sibai proposed the following definition in order to be able to combine and compare the various studies in the literature: hemolysis defined as at least two of the following: 1) lactate dehydrogenase >600 IU/L; 2) presence of schistocytes or; 3) total bilirubinemia >12 mg/L.
Patient demographics including age and sex, medical history, presenting signs and symptoms, and laboratory values [complete blood count, peripheral blood smear examination for schistocytes, reticulocyte count, lactate dehydrogenase (LDH), haptoglobin, total and indirect bilirubin, coagulation tests, Coombs tests, creatinine and ADAMTS13 antigen, activity and antibody levels, if performed] were derived from the medical records.
The diagnosis of TTP in our study was done by demonstration of significant schistocytes (more than 1 percent) on peripheral blood film.
The blood smear showed acanthosis and schistocytes; thrombotic thrombocytopenic purpura (TTP) could not be ruled out because she had hemolytic anemia (hemoglobin, 8.8 g/dL), thrombocytopenia (88 x 1[0.sup.9]6/L), acute renal failure, seizures, and new onset fever (39[degrees]C).
Peripheral smear showed anemia with mild hypochromia, rouleaux, rare spherocytes, thrombocytopenia, mature white blood cells with toxic neutrophils, and absence of schistocytes. Computed tomography of the abdomen and pelvis showed hepatosplenomegaly and lymphadenopathy throughout the chest, abdomen, and pelvis.
Recent studies using a morphological red blood cell module show lower within-run, between-run, and between-observer coefficients of variation when counting schistocytes compared to the coefficients observed for manual assessment.
(6,7) If hemolysis is confirmed, coupled with findings for anemia on the CBC, an increase in the RC, and abnormalities on the peripheral blood smear (eg, schistocytes, bite cells, spur cells), the anemia is likely of the hemolytic type.
However, ADAMTS13 level is normal in CAPS and fewer schistocytes are seen in CAPS compared to TTP and HUS [2].
His Hb was 9.9 gm/dl with a baseline of 10; MCV was 90 Fl; peripheral smear did not show schistocytes.
