Blood Tests (Phlebotomy)

A blood test involves a sample of blood taken for testing 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 or to check your blood count plus vitamin levels.

blood tests at Centric GP

In order to have a blood test carried out it must be requested by one of our GP'S in our practice.

How is a blood test carried out?

  • A blood test usually involves attaching a tourniquet and then gently placing a needle attached to a syringe into one of the veins on the inside of your elbow or wrist.
  • You will feel a sharp prick as the needle goes in but this is not particularly painful.
  • A sample of blood is then taken and the needle is removed.
  • You will be given a cotton-wool pad to put pressure on the site of the injection, which stops any bleeding and should prevent bruising but this can occasionally occur.
  • Most blood tests only take a few minutes to complete.

Some blood tests require several samples taken over a period of time. For example, they may be done to check how you respond to a glucose load for instance. The results can help detect health problems in early stages, when treatments or lifestyle changes may work best.

Your doctor may consider other factors to confirm a diagnosis including; your signs and symptoms, your medical history, your vital signs (blood pressure, breathing, pulse, and temperature) and results from other tests and procedures.
