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.
We do not do blood tests for children under 14 years of age, these would need to be done at the hospital.
If your hospital consultant has advised you to undergo a blood test, please arrange to have it done at either Weymouth Hospital or Dorset County Hospital. Unfortunately, we do not have the capacity to accommodate these tests alongside those requested by our GPs at the surgery.
You can find out more about blood tests, their purpose and the way they are performed on the NHS Choices website.
