What causes high RBC and low Thrombin Time?

High RBC and low Thrombin Time can be caused by many reasons.

If your RBC is in between 4.5 mil/uL and 5.5 mil/uL and your Thrombin Time is in between 14 sec and 23 sec then you need not worry as these are the normal ranges for RBC and Thrombin Time 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
