Blood tests

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
  • check if you have an infection
  • see how well certain organs, such as the liver and kidneys, are working
  • screen for certain genetic conditions

Most blood tests only take a few minutes to complete and are carried out at your GP surgery or local hospital by a doctor, nurse or phlebotomist (a specialist in taking blood samples).
