As the volume of fluid in the blood drops, the RBCs per volume of fluid artificially rises with adequate fluid intake, the hematocrit returns to normal. Dehydration-this is the most common cause of a high hematocrit. Some causes of a high hematocrit include: Polycythemia (also known as polycythaemia or polyglobulia) is a disease state in which the proportion of blood volume occupied by red blood cells increases. Look for Possible Connected Biomarkers: A high hematocrit alongside with a high RBC count and high hemoglobin indicates polycythemia. That is caused by autoimmunity or defects in the red blood cell itself. Excessive destruction of red blood cells. Decreased production of hemoglobin (e.g., thalassemia) Kidney failure-severe and chronic kidney diseases lead to decreased erythropoietin production, a hormone produced by the kidneys that stimulate RBC production by the bone marrow. Bone marrow disorders such as aplastic anemia, myelodysplastic syndrome, or cancers such as leukemia, lymphoma, multiple myeloma, or other cancers spread to the marrow. Damage to the bone marrow from, for example, a toxin, radiation or chemotherapy, infection, or drugs. Excessive loss of blood from, for example, severe trauma, or chronic bleeding from sites such as the digestive tract (e.g., ulcers, polyps, colon cancer), the bladder or uterus (in women, heavy menstrual bleeding, for example). Chronic inflammatory diseases or conditions. Nutritional deficiencies such as iron, folate, or B12 deficiency. It can also be defined as a lowered ability of the blood to carry oxygen. Please consult a physician for specific treatment recommendations.Look for Possible Connected Biomarkers: Low hematocrit + low RBC count + low hemoglobin indicates anemia.Īnemia is usually defined as a decrease in red blood cells (RBCs) or hemoglobin in the blood.
