  • When clinical picture was combined with laboratory finding of macrocytic anemia, a diagnosis of hypothyroidism was made. (bioscientifica.com)
  • However, if the anemia is non-regenerative, then decreased bone marrow production is causing the anemia, although hemorrhage or hemolysis could also be occurring. (eclinpath.com)
  • Remember that the bone marrow takes 3 to 5 days to respond to an anemia, therefore an acute hemorrhagic or hemolytic anemia may initially appear non-regenerative. (eclinpath.com)
  • Because immature anucleate RBC are frequently larger and contain less hemoglobin than mature RBC, a regenerative anemia may have macrocytic (high MCV) hypochromic (low MCHC) RBC indices and a high red blood cell distribution width (RDW). (eclinpath.com)
  • ie, low MCV indicates microcytic (small average RBC size), normal MCV indicates normocytic (normal average RBC size), and high MCV indicates macrocytic (large average RBC size). (medscape.com)

  • Blood diseases might entail abnormalities with red blood cells, white blood cells, platelets, blood arteries, bone marrow, lymph nodes, or proteins involved in bleeding and clotting. (icloudhospital.com)
  • Pancytopenia is a condition when there are too low red blood cells, white blood cells, and platelets. (icliniq.com)

  • The child is having pancytopenia presentation means WBC 9white blood cells), platelet, and hemoglobin are all low. (icliniq.com)

  • This appearance is most frequently observed in conditions that cause bone marrow expansion, such as severe anaemia, thalassemia, and sickle cell disease. (passmed.uk)

(atomictherapy.org)
  • While erythrocytes in the fetus are initially produced in the yolk sac then the liver, the bone marrow eventually becomes the main site of production. (lecturio.com)
