Mean Platelet Volume
Also known as: MPV
What Does Mean Platelet Volume Measure?
Mean Platelet Volume (MPV) measures the average size of platelets in your blood, reported in femtoliters (fL). Platelets are tiny cell fragments produced in the bone marrow that play a crucial role in blood clotting and wound healing. The MPV test is typically included as part of a complete blood count (CBC) and provides valuable information about platelet production and activity. Larger platelets are generally younger and more metabolically active, while smaller platelets tend to be older.
Why Does Mean Platelet Volume Matter?
MPV is an important indicator of platelet function and can provide clues about various health conditions affecting the bone marrow, cardiovascular system, and inflammatory processes. Elevated MPV has been linked to increased risk of cardiovascular events such as heart attack and stroke, because larger, more active platelets are more prone to forming dangerous clots. Conversely, a low MPV may signal bone marrow disorders or conditions where platelet production is suppressed. Clinicians often evaluate MPV alongside platelet count, white blood cell count, and other CBC components to gain a more complete picture of a patient's hematological health.
Normal Ranges
Males
7.5–12.5 fL
Females
7.5–12.5 fL
Children
7.0–12.0 fL (varies slightly by age and laboratory)
Causes of High Levels
- Cardiovascular disease and increased risk of heart attack or stroke
- Type 2 diabetes mellitus, which promotes platelet activation and enlargement
- Hypothyroidism, which alters platelet production and turnover
- Inflammatory bowel disease (Crohn's disease and ulcerative colitis)
- Immune thrombocytopenic purpura (ITP), where rapid platelet destruction triggers release of larger, younger platelets
- Smoking and chronic oxidative stress, which stimulate platelet activity
Causes of Low Levels
- Aplastic anemia, where bone marrow fails to produce sufficient blood cells
- Chemotherapy or radiation therapy suppressing bone marrow function
- Megaloblastic anemia due to vitamin B12 or folate deficiency
How to Improve Your Mean Platelet Volume
Diet
- Increase omega-3 fatty acid intake through fatty fish (salmon, mackerel, sardines) to reduce platelet hyperactivity and lower MPV
- Consume antioxidant-rich foods such as berries, dark leafy greens, and colorful vegetables to combat oxidative stress that enlarges platelets
- Limit refined carbohydrates and added sugars, which promote inflammation and platelet activation
- Incorporate garlic and onions into meals, as allicin compounds have natural antiplatelet properties
- Ensure adequate vitamin B12 and folate intake through eggs, legumes, and leafy greens to support healthy platelet size and production
Supplements
- Omega-3 fish oil: 1,000–3,000 mg EPA/DHA daily to reduce platelet aggregation and lower elevated MPV
- Vitamin D3: 1,000–2,000 IU daily, as deficiency is associated with platelet dysfunction and cardiovascular risk
- Magnesium glycinate: 200–400 mg daily to support normal platelet function and reduce activation
- Curcumin (turmeric extract): 500–1,000 mg daily with piperine to reduce platelet aggregation and systemic inflammation
- Coenzyme Q10 (CoQ10): 100–200 mg daily to reduce oxidative stress that contributes to platelet enlargement

Frequently Asked Questions
What does it mean if my MPV is high?
A high MPV means your platelets are larger than average, which typically indicates they are younger and more metabolically active. This can be a sign that your bone marrow is producing platelets rapidly in response to increased destruction or demand. High MPV has been associated with cardiovascular disease, type 2 diabetes, inflammation, and conditions like immune thrombocytopenic purpura (ITP). However, a single elevated result should always be interpreted alongside your platelet count and other lab values by your doctor.
What does a low MPV indicate?
A low MPV means your platelets are smaller than normal, which often suggests that the bone marrow is not producing platelets efficiently. This can occur with conditions such as aplastic anemia, vitamin B12 or folate deficiency, chemotherapy side effects, or autoimmune diseases like lupus. Low MPV combined with a low platelet count can be a sign of a more serious bone marrow problem and warrants further investigation by a healthcare provider.
Is MPV part of a routine blood test?
Yes, MPV is typically reported as part of a complete blood count (CBC), which is one of the most common routine blood tests ordered by doctors. However, not all laboratories automatically flag MPV values or include them in the standard CBC report. If you are curious about your MPV, you can ask your doctor to review it alongside your platelet count and other CBC components.
Can lifestyle changes lower a high MPV?
Yes, certain lifestyle changes may help normalize an elevated MPV. Quitting smoking, following an anti-inflammatory diet rich in omega-3 fatty acids and antioxidants, exercising regularly, managing stress, and maintaining a healthy weight have all been shown to reduce platelet activation and may help bring MPV values into a healthier range over time. Supplements such as fish oil and curcumin may also be beneficial, but always consult your doctor before starting any new supplement regimen.
