An average platelet volume test (MPV) measures the average size of plates in your blood. Plates are blood cells that your bone marrow does. The healthy platelets come together to help your blood with a stoner when you hurt yourself.
When your bone marrow makes new plates, they are larger than the older plates of your blood. What age can your pads be determined by their size, which can help your health care provider diagnose or monitor certain conditions.
An MPV test is often part of a complete blood count (CBC) during routine exams. But your health care provider can also control an MPV test if you show symptoms that suggest a problem with your size or brochure number. These symptoms may include:
- Easy bruises
- The glea bleeding to brush your teeth
- Bleeding that takes longer to stop, even from small cuts
- Heavy menstrual periods
- Blood in your stools, urine or vomit
- Small red spots, brownish or purplish yellow on your skin
- Symptoms of a blood clot, such as stunning, chest pain and swelling of the legs
You generally do not need to prepare yourself specially for an MPV test. You may want to confirm with your health care provider, if you should avoid food or drink in advance, especially if they plan to do other blood tests at the same time.
The MPV test is generally carried out in the office of your health care provider or in a diagnostic laboratory. If the blood tests make you anxious, plan to bring a family member or a friend.
Talk to your insurer to understand if it will cover the cost of your test if you have health insurance.
An MPV test is to take a small blood sample from a vein in your arm. The process usually takes less than five minutes.
During the test
A health care provider or a phlebotomist, a specialist trained in blood test, will probably ask you to sit on a chair. Then they will take a blood sample from your arm, which involves these steps:
- They clean your skin with an antiseptic solution to kill germs.
- They wrap an elastic band on the upper arm, which limits blood circulation and helps your vein inflate.
- They insert a needle into your vein to collect blood in a bottle or a tight -tied tube attached to the needle.
- They remove the needle and band from your arm.
- They put a cotton or bandage on the Aiguille site.
After the test
You can resume your daily activities almost immediately after the test. If you tend to feel dizzy or light after blood samples, remember to bring someone back to help you. Your health care provider may also recommend that you avoid lifting heavy objects for 24 hours.
MPV tests don’t have much risk. You may experience slight pain or bruises on the needle site, but these symptoms disappear quickly.
In rare cases, you can undergo more serious complications, such as excessive bleeding, infection on the needle site or nerve lesions. Immediately talk to a health care provider if you have these complications.
Your results may be available in a few hours or the next day. You can often see your results on the online portal of your health care provider or your laboratory, or your health care provider can contact you to discuss the results.
Interpret your results
The results are generally reported in femtoliters (FL). This unit measures a very small amount of liquid, comparable to the size of a single brochure. The normal results of the average platelet volume can range from around 7.5 to 12 femtoliters, but this beach can vary depending on different factors, including the laboratory.
A high MPV result suggests that your bone marrow makes new plates at an increased pace. A low MPV result suggests that your bone marrow does not make enough platelets.
High MPV
A high MPV result suggests that your smaller and older pads are quickly destroying, causing the production of newer and larger pads. This may be due to:
- Thrombocytopenia:: A condition where you don’t have enough plates
- Preeclampsia: A complication of pregnancy which causes high blood pressure
- Diabetes: Chronic disease affecting your insulin and blood sugar
- Hemolytic anemia: A type of anemia that occurs when red blood cells are destroyed too early
- Myeloproliferative diseases: A group of blood cancers in which the bone marrow produces too many plates or other blood cells
- Heart disease: Conditions that affect the heart and blood vessels
Low MPV
A low MPV result may suggest that your bone marrow does not produce enough new plates, so most of your pads are smaller and older. This may be due to:
- Some cancers: Including colorectal, gastric, pancreatic, kidney, pulmonary, uterine and other cancers
- Aplastic anemia: A type of anemia where your bone marrow does not produce enough blood cells
- Infections: Including many bacterial or viral infections
- Immune diseases: Like Crohn’s disease, rheumatoid arthritis and lupus
- Alcohol consumption disorder: A disorder involving difficulty controlling your alcohol consumption
An average plattttmaic blood test (MPV) measures the average size of your platelets, which can help health care providers detect platelet -related problems and monitor certain health problems. It is often carried out as part of a complete blood count (CBC). It’s fast and you don’t need to take special measures to prepare for it.
