The Red Blood Cell Distribution Width (RDW) Calculator assesses the variation in red blood cell (RBC) width, a vital component of complete blood count reports.
Typically, RBCs measure between 6-8µm in size, but certain disorders can cause significant deviations. Higher RDW values indicate greater size variation. The normal reference range for human RBCs is 11-14%. In cases of anemia, RDW test results are often combined with mean corpuscular volume (MCV) results to determine the underlying cause. Explore RDW levels efficiently with our calculator.
