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 an abbreviated form of âRed blood cell Distribution Widthâ and helps in the calculation of different sizes of red blood cells that are present in a particular volume of blood sample.
