Hemoglobin is a protein in red blood cells that carries oxygen and carbon dioxide. Adult hemoglobin contains two alpha and two beta globulin chains. Hemoglobin is measured in grams per deciliter of whole blood
Hematocrit measures percentage of red blood cells in blood. Hemoglobin carries oxygen and carbon dioxide in red blood cells. Both tests are part of complete blood count (CBC)
CBC evaluates blood cell composition and quality in a sample. Normal RBC count ranges from 4.1-6.1 million cells/mcL. Values can vary by age, sex, and race
Hemoglobin is a protein in red blood cells that transports oxygen. It consists of heme groups with iron atoms and four globin chains. Oxygen binds to iron in lungs, then releases to tissues. Hemoglobin helps remove carbon dioxide from tissues
Carboxyhemoglobin is a stable complex of carbon monoxide and hemoglobin. Each red blood cell contains 250 million hemoglobin molecules. Carbon monoxide binds hemoglobin 240 times more strongly than oxygen
CBC measures blood cells, hemoglobin, hematocrit, and white blood cell differential. Test helps diagnose diseases and monitor health conditions. Results compared to reference ranges for 95% of healthy people
