According to Medscape, RDW stands for red cell distribution width; it is a measure of the variation of red blood cell size or volume. Higher RDW means a larger variation in the sizes of red blood cells found in a sample.
An RDW test is a red cell distribution width test, which is one of the parameters measured in blood tests, states Medscape. Higher RDW results mean that the patient's red blood cells have a greater variation in size or volume.
"RDW-CV" and "RDW-SD" are a measurement of the size of red blood cells, according to Med-Health.net. RDW-SD is an actual measurement, while RDW-CV involves some calculations using the RDW-SD deviation.

High RDW, or red cell distribution width, is sometimes caused by liver disease, according to Medscape.com. In this case, the mean corpuscular volume, or MCV, is also elevated. These test results are possible indicators of hemolytic anemia, a condition where red blood ce...
