A blood test is taking a sample of blood for testing in a laboratory. Blood tests have a wide range of uses and are one of the most common types of medical test.

For example, a blood test can be used to:

  • assess your general state of health
  • confirm the presence of a bacterial or viral infection
  • see how well certain organs, such as the liver and kidneys, are functioning
  • screen for certain genetic conditions such as cystic fibrosis or spinal muscular atrophy

Most blood tests only take a few minutes to complete and are carried out at your GP surgery or local hospital.

  • How do I prepare for a blood test?

    The healthcare professional who arranges your blood test will tell you whether there are any specific instructions you need to follow before your test.

    For example, depending on the type of blood test, you may be asked to:

    • avoid eating or drinking anything, apart from water (fasting)
    • stop taking a certain medication
  • How do I arrange for a blood test?

    Your GP may provide phlebotomy (blood testing) services in your own surgery.

  • What happens during a blood test?

    A blood test usually involves taking a blood sample from a blood vessel in your arm.

    The arm is a convenient part of the body to use because it can be easily uncovered. The usual place for a sample to be taken from is the inside of the elbow or wrist, where the veins are relatively close to the surface.

    When the sample has been taken, the needle will be removed. Pressure is applied to the tiny break in the skin for a few minutes using a cotton-wool pad to stop the bleeding and to prevent bruising. A plaster may then be put on the small wound to keep it clean and prevent infection.

  • What happens after the blood test?

    Only a small amount of blood is taken during the test so you shouldn't feel any significant after-effects.

    However, some people do feel dizzy and faint during and after the test. If this happens to you, tell the person carrying out the test so they can help you feel more comfortable.

    After a blood test, you may have a small bruised area on your skin where the needle went in. Occasionally, a larger area of bruising may appear. This can be because there was a lack of pressure at the site of the jab or the blood vessel was damaged by the needle.

  • How do I get my blood test results?

    After the blood sample has been taken, it will be put into a bottle and labelled with your name. It will then be sent to a laboratory where it will be examined. The results are sent back to the requesting clinician, and you will be told when and how you will be given them.
