What does 18.5 RDW means?

An RDW of 18.5 refers to the Red Cell Distribution Width, which is a measurement of the variation in red blood cell size. A higher RDW value typically indicates a greater range of red blood cell sizes, which can be seen in conditions such as anemia or nutritional deficiencies. It is important to consult a healthcare provider for interpretation of specific RDW values in the context of an individual's health.
