What is an MPV blood test?
MPV stands for mean platelet volume. Platelets are small blood cells that are essential for blood clotting, the process that helps you stop bleeding after an injury. An MPV blood test measures the average size of your platelets. The test can help diagnose bleeding disorders and diseases of the bone marrow.

What is it used for?
An MPV blood test is used to help diagnose or monitor a variety of blood-related conditions. A test called a platelet count is often included with an MVP test. A platelet count measures the total number of platelets you have.
Why do I need an MPV blood test?
Your health care provider may have ordered an MPV blood test as part of a complete blood count (CBC), which measures many different components of your blood, including platelets. A CBC test is often part of a routine exam. You may also need an MPV test if you have symptoms of a blood disorder. These include:
- Prolonged bleeding after a minor cut or injury
- Small red spots on the skin
- Purplish spots on the skin
- Unexplained bruising
What happens during an MPV blood test?
During the test, a health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.
Will I need to do anything to prepare for the test?
You don't need any special preparations for an MPV blood test. If your health care provider has ordered more tests on your blood sample, you may need to fast (not eat or drink) for several hours before the test. Your health care provider will let you know if there are any special instructions to follow.
Are there any risks to the test?
There is very little risk to having a blood test. You may have slight pain or bruise at the spot where the needle was put in, but most symptoms go away quickly.
