An ear infection is an inflammation of the middle ear, usually caused by bacteria, that occurs when fluid builds up behind the eardrum. Anyone can get an ear infection, but children get them more often than adults. Five out of six children will have at least one ear infection by their third birthday.
Red blood cell distribution width is a way for scientists to measure red blood cell volume and size. When red blood cells are larger than normal, that could indicate a problem. The reference range for RDW is as follows: RDW-SD: 29-46 fL.
RDW is a medical abbreviation that stands for Red Blood Cell Distribution Width. It is a measurement of the size of red blood cells. RDW is routinely tested for during a Complete Blood Count, CBC. A normal RDW range for adults is 10.2 - 14.6. Expect normal RDW to vary from testing lab to testing lab. Low values can suggest anemia while high values are sometimes seen in liver disease and vitamin B -12 deficiency cases. An interesting fact about higher than normal RDW results is that it is a strong predictor of early death.
