What causes high RDW and low ALT SGPT?

High RDW and low ALT SGPT can be caused by many reasons.

If your RDW is in between 11.6 % and 14 % and your ALT SGPT is in between 21 U/L and 72 U/L then you need not worry as these are the normal ranges for RDW and ALT SGPT 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
