Blood Tests

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

X-Ray

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 a 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.
