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 childs hand will be anaesthetised (numbed) with a special cream before the sample is taken.
It is essential that you contact reception after 2 weeks to check that all your results are back and to ask what your doctor has said about them. Results can sometimes go missing between surgery and lab so please never assume that no news means good news.
Our reception staff are not qualified to comment on results therefore it is your responsibility to check them and make any necessary follow-up appointment with the doctor if asked to do so.
