Amount of hemoglobin hematocrit and hemoglobin polycythemia vera. Medical search. Frequent questions

A reduced value denotes anemia (of any cause) while a high hematocrit may indicate dehydration (e.g. burns, vomiting, diarrhoea), increased red cell production (erythrocytosis due to any cause) or malignant proliferation of red cells (polycythemia vera). (ndtv.com)
Dehydration produces a falsely high hematocrit that disappears when the proper fluid balance is restored. (medicinenet.com)
High levels of Hematocrit can be the result of dehydration, diarrhea, erythrocytosis or myeloproliferative disorders such as Polycythemia Vera. (targetwoman.com)
In contrast, high hemoglobins may point to dehydration or other medical conditions that need further investigation by a doctor. (healthyious.com)
If your haematocrit levels are higher than normal, this can be due to dehydration, or a disorder such as polycythemia vera, that causes your body to produce too many red blood cells. (goodbodyclinic.com)

Secondary polycythemia would more accurately be called secondary erythrocytosis or erythrocythemia, as those terms specifically denote increased red blood cells. (medscape.com)
[ 8 ] No other causes of polycythemia/erythrocytosis are associated with elevated granulocyte or platelet counts. (medscape.com)
If too much erythropoietin is produced, as occurs with some benign or malignant kidney tumors and with a variety of other cancers, too many red blood cells may be produced (polycythemia or erythrocytosis). (healthjade.com)
Erythrocytosis is a relative or absolute increase in the number of circulating RBCs, resulting in the PCV, hematocrit, RBC count, and hemoglobin concentration increasing above reference intervals. (merckvetmanual.com)
however, polycythemia may imply leukocytosis and thrombocytosis, in addition to erythrocytosis. (merckvetmanual.com)

Thus, in a patient with severe anemia, the relative amount of reduced hemoglobin in the venous blood may be very large when considered in relation to the total amount of hemoglobin. (medenosrce.net)
However, since the concentration of the latter is markedly reduced, the absolute quantity of reduced hemoglobin may still be small, and therefore patients with severe anemia and even marked arterial desaturation do not display cyanosis. (medenosrce.net)
This leaves 25 percent of the hemoglobin in the reduced form, an amount likely to be associated with cyanosis in the absence of anemia. (medenosrce.net)
Hemoglobin concentration (Hb) is used clinically to determine the presence of anemia, which is functionally defined as insufficient red blood cell (RBC) mass to adequately deliver oxygen to peripheral tissues. (medscape.com)
3] Anemia is considered to be present if the Hb or the hematocrit (Hct) is below the lower limit of 2 standard deviations (-2SD) or the 95% confidence interval for the normal population. (medscape.com)

However, in the case of Polycythaemia vera, a rise in the erythrocyte count provides the organ with a higher amount of oxygen, which leads to a decline in the production of erythropoietin. (aop-health.com)
It also measures the amount of substance in the blood that carries oxygen (hemoglobin) and the percent of whole blood that is made up of red blood cells (hematocrit). (lls.org)
Hemoglobin is a protein in your red blood cells that carries oxygen from your lungs to the rest of your body. (medlineplus.gov)
However, hypoxemia secondary to chronic pulmonary disease, sleep apnea, morbid obesity, cardiac shunts and high altitude also can cause physiological rise of hemoglobin levels to improve oxygen delivery to the tissues. (symptoma.com)
Chronic pulmonary disease (e.g., emphysema-abnormal distension of the lungs with air) may produce chronic hypoxemia (reduced oxygen tension in the blood) and lead to absolute polycythemia. (symptoma.com)
The increase in the quantity of reduced hemoglobin in the cutaneous vessels which produces cyanosis may be brought about either by an increase in the quantity of venous blood in the skin as the result of dilatation of the venules and venous ends of the capillaries or by a reduction in the oxygen saturation in the capillary blood. (medenosrce.net)
