What does low hematocrit and hemoglobin mean

If a patient is severely dehydrated, the hemoglobin and hematocrit will appear higher than if the patient were normovolemic if the patient is fluid overloaded, they will be lower than their actual level. When so assayed, it is subject to the vagaries inherent in obtaining an accurate measurement of the MCV (see Chapter 152).Р”В«oth the hemoglobin and the hematocrit are based on whole blood and are therefore dependent on plasma volume. Hematocrit levels that are too high or too low can indicate a blood disorder, dehydration, or other medical conditions. Automated cell counters calculate the hematocrit by multiplying the red cell number (in millions/mm 3) by the mean cell volume (MCV, in femtoliters). A hematocrit test measures how much of your blood is made up of red blood cells.Red blood cells contain a protein called hemoglobin that carries oxygen from your lungs to the rest of your body. Pt with true polycythemia with an increased red blood cell (RBC) mass. This value can be determined directly by microhematocrit centrifugation or calculated indirectly. Differential Diagnosis for Hemoglobin and Hematocrit. The normal hematocrit for men is 40 to 54% for women it is 36 to 48%. The hematocrit measures the volume of red blood cells compared to the total blood volume (red blood cells and plasma). An erythrocytosis is the consequence of too many red cells this results in hemoglobin levels above normal. The hematocrit measures the volume of red blood cells compared to the total blood volume (red blood cells and plasma). What happens when your hemoglobin and hematocrit is low When the hemoglobin level is low, the patient has anemia. They are different ways to measure the red blood cells in your bloodstream. Anemia: A low hemoglobin or hematocrit means you have anemia. An erythrocytosis is the consequence of too many red cells this results in hemoglobin levels above normal. Hematology and Oncology 31 years experience. When the hemoglobin level is low, the patient has anemia.

The normal Hb level for males is 14 to 18 g/dl that for females is 12 to 16 g/dl. People with polycythemia have an increase in hematocrit, hemoglobin, or red blood cell count above the normal limits. The amount of hemoglobin in whole blood is expressed in grams per deciliter (g/dl). What does it mean if your RBC hemoglobin and hematocrit are high Polycythemia definition Polycythemia is a condition that results in an increased level of circulating red blood cells in the bloodstream. To ensure adequate tissue oxygenation, a sufficient hemoglobin level must be maintained. Hemoglobin (Hb) is the protein contained in red blood cells that is responsible for delivery of oxygen to the tissues.
