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.
You can find out more about blood tests, their purpose and the way they are performed on the NHS Choices website.
Unfortunately it is not possible for children under 16 years old to have blood tests performed at the surgery. The doctor will inform you how to arrange for a child’s blood test to be arranged either at Kidderminster Treatment Centre, or at The Corbett Hospital.
