According to the American Association for Clinical Chemistry, MCHC is the mean corpuscular hemoglobin concentration, a calculation of the average percentage of hemoglobin inside a red blood cell. The mean corpuscular hemoglobin is a calculation of the average amount of oxygen-carrying hemoglobin inside a red blood cell.Know More
The American Association for Clinical Chemistry notes that other red blood cell indicators reflect the mean corpuscular volume, which is a measurement of the average size of red blood cells. Additionally, the red cell distribution width indicates the calculation of the variation in the size of red blood cells.
Evaluation of red blood cells is part of the complete blood cell count lab screening test that determines the general health of an individual. According to the American Association for Clinical Chemistry, red blood cell evaluation and hemoglobin evaluation align. Hemoglobin is a protein that carries oxygen in the blood. Anemia results from a low level of hemoglobin. Causes of anemia include acute or chronic bleeding, red blood cell destruction (known as hemolytic anemia), certain nutritional deficiencies, bone marrow disorders or damage, chronic inflammatory disease and kidney failure. Polycythemia indicates high levels of hemoglobin; its causes are dehydration, lung disease, kidney or other tumor that produces excess erythropoietin, smoking, certain genetic causes and polycythemia vera.
Complete blood cell counts also evaluate white blood cell count, white blood cell differential, the evaluation of platelets and the body's reticulocyte count. This measures the absolute count of young red blood cells present.Learn more about Diagnostics & Imaging
The most common blood test, the complete blood count, or CBC, measures red blood cells, white blood cells, hemoglobin, hematocrit, platelets and mean corpuscular volume of the blood, according to the National Heart, Lung and Blood Institute. This test is often used to check symptoms and diagnose a wide variety of conditions, such as anemia, infections, blood cancers, clotting problems and immune system disorders.Full Answer >
Mean corpuscular hemoglobin (MCH), according to MedlinePlus, is the measure of the hemoglobin content of red blood cells. Hemoglobin, found within the red blood cells, transports oxygen from the lungs to the rest of the body. The normal range for MCH is 27 to 31 picograms per cell. More than 31 picograms per cell is hyperchromic anemia, while less than 27 picograms per cell is hypochromic anemia.Full Answer >
A person needs to fast for 8 to 12 hours before a blood test. Fasting is necessary so that accurate results can be reported.Full Answer >
Numerous blood tests require fasting for up to 12 hours before the test, including lipid profile, renal function panel, glucose level, chem 7, basic metabolic profile, comprehensive metabolic profile and vitamin B-12, says Adams Memorial Hospital. Other fasting tests include tests for iron levels and liver function.Full Answer >
