Blood Tests

Note: see Tests & Results for more information about how to get your blood test results.

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

A blood test usually involves the phlebotomist taking a blood sample from a blood vessel in your arm. and the usual place for a sample is the inside of the elbow or wrist, where the veins are relatively close to the surface. Blood samples from children are most commonly taken from the back of the hand. The child’s hand will be anaesthetised (numbed) with a special cream before the sample is taken.

You can find out more about blood tests, their purpose and the way they are performed on the NHS website.

Unused Blood

The laboratory at the Royal Shrewsbury Hospital use any surplus blood that is left after required tests have been carried out for training purposes. If any patient has objection they must specify this at the time of their appointment.
