General information

Blood tests, sometimes referred to as phlebotomy, have a wide range of uses and are one of the most common types of medical tests.

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 and screen for certain genetic conditions.
