Blood Test, X-Ray Information

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.   For some children, it may be more appropriate for the doctor to arrange the test  within a hospital based clinic.

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.

X-rays are carried out at Newham University Hospital NHS Trust, E13 8SL (0207 363 8924) and at Shrewsbury Road, E7 8QP (0208 586 5236). The opening hours are: 9:00 am – noon; 2:00 pm – 4:30 pm.
