Can Polycythemia Be Hereditary What Is The Gene For Too Many Red Blood Cells
Maybe "genetic risk: Polycythemia can be acquired. It is a natural respohse to living on a high mountain. There are oxygen censors in the brainstem and if oxidation is compromised a signal goes to the kidney to produce erythropoietin. This then signals the bone marrow to produce more red cells to compensate for the rarefied air. Exactly the same thing can happen with vitamin b1 deficiency induced by excess of sugar. ...Read moreSee 1 more doctor answer
From a medical standpoint, "genetic" refers to the potential heritability of various medical conditions. While some conditions are inevitable (at some point in one's life) as a consequence of simple genetic heritability (eg huntington's disease), a large number of medical conditions (including all behaviorial health disorders) are the expressed final pathway of a ...Read more
My red blood cells are too small to carry enough haemoglobin, what is the name of this anemia and is it common?
In thalassemia, why there is nucleated red cells as the bone marrow is desperately trying to get red cells into the circulation as fast as possible?
Hiya, what are the causes of sickle cell anemia? I know it is inherited but i need it explained in a way that can tell me the causes of gene mutation.
Gene mutations: are random. The sickle gene confers some resistance to malaria due to the abnormal configuration of hemoglobin. Sickle trait/sickle cell anemia is most prevalent in populations where malaria is or was endemic. It is likely that the mutation conferred some competitive advantage due to its antimalarial effects and was promulgated through natural selection. ...Read moreSee 1 more doctor answer
Is this your Hemoglo: Red cell count runs into 4-5 million cell count range. If yours is 6...You probaly are talking about hemoglobin(hb) level. This is normally 12-14 grams. Anything less than 12 is called anemia. Anything below 10 grams will make you feel weak, and less than 8 grams requires a blood transfusion. So you should go see your doctor and find the cause which will require doing further tests. ...Read more
Erythrocytosis: Too many red blood cells can be problematic and there are a few causes of this condition. A hematologist is best qualified to evaluate and treat Erythrocytosis or polycythemia. ...Read more
Does sickle cell nemia has treatment? If so what are the medications? What are the foods that achild with sickle cell anemia eat? Is it tur that when some body reaches the age eighteen the disease disapears
Many questions: Sickle cell anemia is genetic and never disappears without bone marrow transplantation. Sickle cell anemia has medications that improve outcomes. Penicillin prophylaxis, empiric treatment of fever with antibiotics, and Prevnar (pneumococcal vaccine) / Pneumovax immunizations decrease risk of dying from infection. Hydroxyurea can decrease the frequency of painful crises and may minimize / delay sickle cell damage to body ...Read moreSee 1 more doctor answer
Many causes.: Low WBC can be due to nutritional factors, infections (esp. Viral infections), autoimmune diseases, inhereted defects, leukemias and other bone marrow cancers, meylodysplasia, drug reactions, and even unknown causes. The problem with this is infection, but the risk depends on how low the WBC is. Only with very low WBC is there a risk of death. ...Read more
Which type of anemia is more serious and could be due to bloo cancer? Is it macrocytic or microcyyoc anemia? Mcv 107 is it too high? Thanks
Both: Microcytic anemia is most often due to iron deficiency and blood loss. Macrocytic anemia(mcv over 96) can be due to vitamin B12 or Folic Acid deficiency, alcoholism, liver disease, some bone marrow disorders like leukemia, underactive thyroid or rarely fish tapeworms. All anemias are dangerous if not properly diagnosed and treated. A hematologist is consulted if the cause of the macrocytosis is vague. ...Read moreSee 2 more doctor answers
Causes of consistently high RBC and other red blood cell values in a younger person? Is it serious and what Doctor handles this?
When donating a kidney, what is the blood type that is universal? Explain the different blood types for donating. Ex: Rh can donate to a+ etc...
ABO blood type: In this system of red cell antigens, O is considered to be recessive. Someone with type O blood would have two O alleles. People with type A blood can have two A alleles or one A allele and one O allele. Same with blood type B. This makes O the recessive and A and B are dominant. ...Read more

What is the signifigance of a mono clonal T cell beta gene rearrangement found in blood ? All other labs are normal. Is this a sign of lymphoma ?
Probably not: Monoclonal populations of immune cells can be a challenge to diagnose. Conditions like RA can associate with t-cell monoclonal populations. If the counts are otherwise normal, the group of cells should be followed but probably do not represent malignancy per se, though technically are a "neoplastic" proliferation of cells. http://www.ncbi.nlm.nih.gov/pubmed/18474096 Check with your doctor. ...Read more
I know that the typical test for sickle-cell anemia is a hemoglobin electrophoresis, but will you be able to see the sickle shape of the blood cells?
Yes: Sick led cells are readily seen on a peripheral blood smear. It's worth knowing that the irreversibly sick led cells that you see on a smear are not necessarily the ones that cause the problem. In order for a cell at risk for sickling to occlude the small blood vessels (capillaries), they first must be able to enter them. In other words they must be deformable. They become occlusive in the vessel. ...Read moreSee 1 more doctor answer
Polycythemia vera(P.: P. Vera is a condition where the bone marrow makes too many red cells and the hemoglobin gets above 18-20 Gms (normal up to 16 grams). it is considered a Myeloproliferative disorder which is a type of low grade cancer although most people live for 10-20 years and some new treatments have recently become available. ...Read more
Diagnosed with giant liver hemagioma size of grapefruit read online that could cause anemia because it sequesters red blood cells is that true ?
Is it possible for a cell to be alive in dried blood? Ie. Rbc, white cells or any cell that could be in the bloodstream? How soon do they die?
No: Cells are living things and require a certain amount of moisture to live. Some viruses and bacteria can survive because of special adaptations, and for that reason we use universal precautions even with dried blood. Certainly the genetic material can remain for longer periods of time. ...Read more
