Results Of Tests And Investigations 

A blood test involves taking a small sample of blood (usually from a vein near the elbow) which is then sent to the hospital laboratory to be analysed to help diagnose an illness, monitor treatment or determine someone’s blood group.

It will usually take 5 working days for your blood result to get back to your doctor.

If your test results are abnormal, your doctor will contact you.

If your tests are normal, you will not be contacted, but if you wish to find out the results of your test, please ring or call during any week day after 10.30am. If your doctor has asked you to return anyway, you should do this, as they may wish to tell you the results of your test in person.

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.
