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 = Red Cell Distribution Width. It's a measure of the variation in size of the red cells counted when your blood was tested. Actually, a low RDW is not always bad.It means that your cells are actually more uniform in size.Its when the number is higher that is of more concern. When the RDW is high, the condition is known as anisocytosis.DW = Red Cell Distribution Width. It's a measure of the variation in size of the red cells counted when your blood was tested. Actually, a low RDW is not always bad.
