Is RDW CV 26.8 high, normal or dangerous? What does RDW CV level 26.8 mean?

📅 Medical Review Date: December 9, 2025

Your RDW CV level of 26.8 is a High RDW CV level.

An RDW CV level of 26.8 % usually means there is wide variation in red blood cell sizes. It suggests mixed or early-stage anemia. High levels of RDW CV can cause fatigue, weakness, pale skin, shortness of breath, dizziness, cold hands and feet, and brittle nails. This can be caused by iron deficiency anemia, vitamin B12 deficiency, folate deficiency, or chronic liver disease. Further tests are often needed to identify the cause and guide appropriate treatment.

High RDW CV levels may indicate underlying health problems. The normal range is typically between 11.6 % and 14 %. If your levels are outside this range, it's important to speak with a healthcare provider. Consulting a doctor is recommended to determine the cause and appropriate next steps.

The normal RDW CV range for men is :11.6 - 14 %

Misdiagnosis is more common than people think—and the consequences can be serious. Delayed treatment, unnecessary medication, or worse. If you want a second opinion on your blood work, one option is to upload it to a site like wholebodyprotocol.com, where world-class doctors review your results. They charge a small fee—around $90 (though you'll want to check the latest price as it fluctuates)—and email you a detailed report. With over 12 million people affected by misdiagnosis every year, that little bit of extra peace of mind can go a long way.

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

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