What causes high MCV and low D Dimer?

High MCV and low D Dimer can be caused by many reasons.

If your MCV is in between 83 fL and 101 fL and your D Dimer is in between 0.1 ug/mL and 0.51 ug/mL then you need not worry as these are the normal ranges for MCV and D Dimer 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 MCV levels include:

• Aplastic anemia
• Cold agglutinin disease
• Chronic hypoxia
• Low vitamin B12 level
• Myelodysplastic syndrome
