What causes high RBC and low Bilirubin total?

High RBC and low Bilirubin total can be caused by many reasons.

If your RBC is in between 4.5 mil/uL and 5.5 mil/uL and your Bilirubin total is in between 0.2 mg/dL and 1 mg/dL then you need not worry as these are the normal ranges for RBC and Bilirubin total 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 RBC levels include:

• Sudden (acute) or chronic bleeding from the digestive tract
• Kidney failure—severe and chronic kidney diseases lead to decreased production of erythropoietin
• Bone marrow damage
• Conditions that cause red blood cells to be destroyed, such as hemolytic anemia caused by autoimmunity or defects in the red cell itself
• Chronic bleeding from the digestive tract
