A blood test is when a sample of blood is taken 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
We do run blood test clinic every morning and they are usually requested by your clinicians.
Blood samples from children are most commonly taken at Starlight unit at Homerton hospital with prebooked appointments
