If you are unable to book online, please call the phlebotomy team on 01438 284044 9-5pm Monday to Friday.

There are some rare tests which may mean you have to go to Lister or Hertford Hospital for which the doctor should inform you.

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 childs 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 Choices website.


An X-ray is a widely used diagnostic test to examine the inside of the body. X-rays are a very effective way of detecting problems with bones, such as fractures. They can also often identify problems with soft tissue, such as pneumonia or breast cancer.

If you have an X-ray, you will be asked to lie on a table or stand against a surface so that the part of your body being X-rayed is between the X-ray tube and the photographic plate.

An X-ray is usually carried out by a radiographer, a healthcare professional who specialises in using imaging technology, such as X-rays and ultrasound scanners.

You can find out more about x-ray tests, how they are performed, their function and the risks by visiting the NHS Choices website.


If the doctor has asked you to telephone for a test result please do so between 14:00 - 16:30.  Most results will be available within 5 working days, although others such as antibody tests can take 2 weeks. 

X-ray results may be back within 10 days.  If you are making an appointment to discuss test results please try and make this with the doctor who arranged the tests.

It is practice policy only to give results of medical tests to the patient (when over 16) not to a relative or representative.

Please note that results of investigations requested by hospital doctors do not always come to us so before making an appointment check with the reception staff first.
