A low hemoglobin count can be associated with a disease or condition that causes your body to have too few red blood cells. This can occur if: Your body produces fewer red blood cells than usual. Your body destroys red blood cells faster than they can be produced. You have blood loss.
Causes for low hematocrit and hemoglobin include malnutrition, bleeding, chronic kidney disease, liver disease, bone marrow disorders, and blood cancers like leukemia or lymphoma. Learn more about hematocrit and hemoglobin and what high or low values say about your health.
Hemoglobin is a protein in your red blood cells. Your red blood cells carry oxygen throughout your body. Oxygen powers your cells and gives you energy. A low hemoglobin level may be a sign of several conditions, including different kinds of anemia and cancer.
For anemia, the test measures the amount of the red blood cells in the blood, called hematocrit, and the level of hemoglobin in the blood. Typical adult hemoglobin values are generally 14 to 18 grams per deciliter for men and 12 to 16 grams per deciliter for women.
Hematocrit. A hematocrit test is a simple blood test that measures the percentage of red blood cells in your blood. Red blood cells are important because they carry oxygen throughout your body. Test results showing low or high hematocrit levels may be signs of blood disorders or other medical conditions. Find a Primary Care Provider.
Anemia is defined as a low number of red blood cells. In a routine blood test, anemia is reported as a low hemoglobin or hematocrit. Hemoglobin is the main protein in your red blood cells.
Low levels of the protein in red blood cells that carry oxygen, called hemoglobin, is the main sign of anemia. Some people learn they have low hemoglobin when they donate blood. If you're told that you can't donate because of low hemoglobin, make a medical appointment.
Health Library / Diseases & Conditions / Anemia is when you have low levels of healthy red blood cells to carry oxygen throughout your body. Symptoms include fatigue, weakness and feeling short of breath. They can be mild or severe. Anemia may be life-threatening. Many things may cause it and there are different types of the condition.
A low hemoglobin concentration and/or low hematocrit are the parameters most widely used to diagnose anemia. The reference range depends on age and sex of the patient, as well as other factors such as altitude, prevalence of smoking in the normative population, and other factors. The table summarizes reference ranges for the CBC (table 1).
Anemia is a decrease in the number of red blood cells (RBCs) as measured by the red cell count, the hematocrit, or the red cell hemoglobin content. In adult males, anemia is defined as any of the following: Hemoglobin < 13.6 g/dL (< 1360 g/L) Hematocrit < 40% (< 0.40) RBC < 4.5 million/mcL (< 4.5 × 1012/L)
