Your health care provider may have ordered a complete blood count, which includes an MCV test, as part of your regular checkup or if you have symptoms of a blood disorder. These symptoms include:. 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. You don't need any special preparations for an MCV 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. There is very little risk to having a blood test. You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly.
If your MCV levels are not in the normal range, it doesn't necessarily mean that you have a medical problem needing treatment. Diet, activity level, medicines, a women's menstrual cycle, and other considerations can affect the results.
