What causes high RDW and low Creatinine?

High RDW and low Creatinine can be caused by many reasons.

If your RDW is in between 11.6 % and 14 % and your Creatinine is in between 0.9 mg/dL and 1.3 mg/dL then you need not worry as these are the normal ranges for RDW and Creatinine respectively. But if your levels are lesser or greater than the above values, then there may be some problem in your body.

Some examples of conditions that can increase or decrease RDW levels include:

• Crohn's disease
• Chronic liver disease
• Thalassemia, an inherited blood disorder
• An iron or vitamin deficiency
• Heart disease
