Blood Tests

Top Tips From Medway Community Healthcare




Blood tests are carried out to help in the diagnosis, care and treatment of various health conditions and diseases and they may be requested by your GP, your specialist team or nurse. They will give you a blood test form to take to your appointment so that the clinic know which tests to carry out.

Arrive ready for your blood test appointment.

On the day, please bring with you your blood form or F number code (this is given to you by your GP). Please ensure you have any coats off and sleeves rolled up ready for your bloods to be taken.

How to avoid a faint

Fainting can occur when having your blood test. What steps can you take to prevent fainting during your blood test?

Tensing your muscles or crossing your legs at the onset of symptoms may help postpone or prevent fainting. You also may lie down and elevate your legs. If you have fainted at a blood test before, you should ask to do your next blood draw lying down. Tell your phlebotomist immediately if you start to feel light headed.

You can also reduce your likelihood of fainting by doing the following:

  • Try not to skip meals.
  • Don’t fast for too long.
  • Stay hydrated. Ideally, start drinking more fluids the day before your blood test, and continue to drink water up until you have your blood drawn. Staying hydrated helps increase your blood volume. And it plumps up your veins for an easier draw. 
  • Avoid standing for prolonged periods of time.
  • Reduce caffeine and alcohol intake prior to your test.
  • Consider wearing elastic stockings to keep blood from pooling in your legs (which would reduce blood flow to your brain).
  • Don’t look. If getting blood taken makes you queasy, don’t look at the needle during your test. Read, look at your phone — or chat with your phlebotomists. Our team understand that it can be difficult for some people. They’re usually experts at distraction and can put you at ease. 
  • Take a deep breath and relax.  If you’re anxious about your test, take deep breaths. You can also ask the person drawing your blood to explain what they’re doing. Uncertainty can be stressful. The calmer you are, the easier the draw will be, and the quicker you’ll be out of there.
  • Be proactive and talk to the phlebotomist before your blood test and let him/her know if you have fainted before and we will ensure you are tested lying down. It may be useful to be accompanied by a friend or relative who can help take you home if you do faint again.

Booking your blood test

Our clinics are held at a choice of venues and are appointment only clinics - booking an appointment is necessary. 

Blood tests for children

If your child needs a blood test you need to book an appointment online. Blood tests for children often require more time allocated in order for our staff to reassure them and for you to help calm them before the blood test is taken. A booked appointment means you have a set time for the test, which avoids any potential waiting time and so reduces your child’s anxiety levels prior to going in to the clinic.
