What causes high MCH and low MPV?

High MCH and low MPV can be caused by many reasons.

If your MCH is in between 27 pg and 32 pg and your MPV is in between 6.8 fL and 10.9 fL then you need not worry as these are the normal ranges for MCH and MPV 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 MCH levels include:

• An overactive thyroid gland
• Complications from an infection
• An autoimmune disease
• Thalassemia, an inherited blood disorder
• Liver diseases
