Before your test
Before your blood test, a healthcare professional will inform you of any specific instructions to follow. Some tests might require you to stop taking certain medications or to avoid eating and drinking beforehand. You will be informed if this applies to you. It is essential to follow the instructions given to you as it can affect the results of your blood test and may need to be redone.
During your test
During your test, a blood sample will be taken from a blood vessel in your arm. The sample is usually taken from the inside of the elbow or wrist as the veins are close to the surface and easy to access. The area will be cleaned, and a tight band (tourniquet) will be placed on your upper arm to cause the veins to swell and aid the blood drawing process. Your blood will then be drawn using a needle and syringe. You may feel a slight pricking or scratching sensation as the needle goes in, but it shouldn’t be painful. If you don’t like needles or blood, let the person drawing your blood know, and they can ensure you are comfortable during the process.
After your test
Because only a very small amount of blood is taken, there shouldn’t be any significant side effects, but some people report feeling dizzy after the test. You may have a small bruise where the needle went in, but these are usually harmless and fade over the next few days.
Your sample will then be sent to the laboratory, where it will be analysed under and microscope and tested with specific chemicals depending on what kind of blood test you are having. Your results will then be sent to you by email. If you would like to discuss your results further, you can take them to your own GP, or for an extra charge you can discuss them with one of our private GP’s. Test result turnaround will depend on the type of test you have had.
