One could have the opposite disorder of too many red blood cells and this is known as erythrocytosis. One could have red cells that are filled with unusual hemoglobin such as the thalassemias. ...Read more

Chronic anemia due to slow blood loss, like menstrual loss, peptic ulcer disease, iron, b12, folate (folic acid) deficiencies, hypothyroidism, chemotherapy, drugs etc. ...Read more
What are the functions of the different parts of blood (red blood cells, white blood cells, platelets, plasma)?
All childhood blood disorders that cause bone marrow to produce cells but slowly, low red cells white and platelets, B12 and iron are all in range?
Many conditions: Pancytopenia, or decrease in rbc, wbc, and platelets can be genetic, like Fanconi anemia or Dyskeratosis congenital, that include other abnormalities. Acquired pancytopenia, besides low B12 and Folate, (folic acid) can be caused by a toxin, drugs, radiation, a viral infection, malnutrition and myelodysplastic syndrome (MDS). If a cause is not found, it is said to be idiopathic. I hope it resolves. ...Read more
Often a virus!: While blood cell count can be low with viral infections. Important to make sure that the red blood cell count and hemoglobin are normal and that the while blood cells are normal in appearance. If wbc, rbc and platelets are low, intervention by hematologist is necessary and may require bone marrow. Low WBC should be followed and return to normal when over the viral infection! ...Read more
Is there any difference between osmotic fragility of fetal red blood cells and adult red blood cells?
Let me help: Anabolic steroids, which stimulate red blood cell production carbon monoxide poisoning, congenital heart disease in adults, copd, dehydration, epo doping (injections of erythropoietin (epo) to enhance athletic performance), heart failure, hemoglobinopathies (conditions present at birth that impair the oxygen-carrying capacity of red blood cells) and others. Please read below link. ...Read more
Quite a few: Things. The most common thing would be an acute infection, usually bacterial. Also could be seen in a heavy smoker, other stressful illness and myeloproliferative diseases. How high? ...Read more
When both RBC and: Wbcs are affected several topics come to mind. The marrow may be stressed in response to infection, or due to a medication. This would also be a common pattern in bone marrow production problems such as the myelodysplastic syndromes. Patients with acute leukemia can also present in this fashion. ...Read more
What do the red blood cells look like under the microscope in iron deficiency and in pernicious anemia? Any other blood cells affected?
Two distinct looks..: Fe deficiency causes a hypochromic microcytic anemia, which means the cells are smaller than normal and have decreased pigment. The zone of central clearing in a red cell (normally 1/3 its diameter) is significantly increased. In pernicious anemia, the red cells are enlarged (aka, macrocytic). You may also see changes in neutrophils, such as increased nuclear segmentation (>6). ...Read more
