What happens during a TP53 genetic test?A TP53 test is usually done on blood or bone marrow.If you are getting a blood 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.If you are getting a bone marrow test, your procedure may include the following steps:You'll lie down on your side or your stomach, depending on which bone will be used for testing. Most bone marrow tests are taken from the hip bone.Your body will be covered with cloth, so that only the area around the testing site is showing.The site will be cleaned with an antiseptic.You will get an injection of a numbing solution. It may sting.Once the area is numb, the health care provider will take the sample. You will need to lie very still during the tests.The health care provider will use a special tool that twists into the bone to take out a sample of bone marrow tissue. You may feel some pressure on the site while the sample is being taken.After the test, the health care provider will cover the site with a bandage.Plan to have someone drive you home, since you may be given a sedative before the tests, which may make you drowsy.
