A hemoglobin test is done to check for low or high levels of red blood cells. This leads to increased blood volume and viscosity. Polycythemia (sometimes referred to as erythrocytosis) is defined as an absolute increase in red blood cell (RBC) mass, most commonly suspected in the context of an elevated hemoglobin, hematocrit, or RBC count. In general, the hemoglobin level and hematocrit rise when the number of red blood cells increases. Normal reference range for hemoglobin for children, men and women are 11-13 g/dL, 14-18 g/dL, and 12-16 g/dL respectively.

Anemia Hemoglobin and Hematocrit is a topic covered in the Davis's Lab & Diagnostic Tests. Monitoring hemoglobin and hematocrit closely is also essential in the course of PPH including the assessment of transfusion needs. Hemoglobin level is directly related to functional measures such as oxygen availability, [29] fractional oxygen extraction [30] and RBC transport, [31] but these predictable effects have not been clearly demonstrated to be better indicators for transfusion. It is advised that detailed evaluation of anemia is performed if the hematocrit level is below 37 percent, or 33 percent in women of child bearing age.

From 12 to 15 years old the level changes to 12.0 g / dL. Children: varies with age ; If the RBC and the hemoglobin are both normal, it is possible to estimate the hematocrit as being approximately three times the hemoglobin. Hemoglobin is a protein in red blood cells that helps blood carry oxygen throughout the body. A high hemoglobin count indicates an above-normal level of the iron-containing protein in red blood cells. MCHC levels are measured during a complete blood test to identify the amount of hemoglobin in a single blood cell. 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. Living a healthy lifestyle can likewise impact hemoglobin and hematocrit levels.
