Patients may need to undergo blood tests to aid the diagnosis of illnesses. Blood tests are undertaken in our outpatient departments by phlebotomists.
Some blood tests require a patient to fast for a period of time before the blood test is undertaken. Your GP or consultant will tell you if this is the case.
To safely manage the flow of patients and avoid overcrowded waiting areas we use a booking system for blood tests.
Please ensure that you bring along the blood test request form that was given to you by your GP or consultant.
To book a blood test appointment please select a location below

How should you prepare a child for attending?
Make sure you bring the printed form your doctor gave you.
Make sure they keep warm and drink plenty of fluids (water only if it's a fasting test). If you / the child are anxious, you can apply local anaesthetic / Emla cream or its equivalent to both inner elbows 90 minutes before the test; please see information about this below.

What should an adult patient do before attending?
Please drink plenty of fluids (water only if you were advised to fast) and keep warm.
Bring the form you were given by your doctor if required.
-
Should I book a paediatric (10 and under) or a 10+ appointment for a 10 year old?
Either is fine! If your 10 year old is nervous, a paediatric appointment may be best - but book whichever appointment suits you and the child.

Information on the use of numbing creams for children
It is recommended that any child over 1 month of age is to be offered a local anaesthetic cream prior to their procedure. This helps to reduce pain caused by the insertion of the needle. Your GP can prescribe anaesthetic cream, or you can buy it over the counter at a pharmacy.
The places suggested to take blood or cannulate include the back of both hands and inside both elbows (antecubital fossa). The healthcare professional taking the blood will select the best site when your child is in the blood test centre.
The local anaesthetic should be applied to all four areas: back of both hands and the creases of both elbows, prior to the procedure.
It may be necessary to apply the cream to the top of the feet if there have been difficulties obtaining blood in the past. We recommend that you do not leave the cream on for longer than the suggested time as this gives no further benefit. Cream should NOT be applied to broken skin or wounds, or if the child has active eczema.
Please do not let your child lick the cream. If this happens, encourage them to drink plenty of water and call 111 if you are concerned that they have swallowed a large amount.
Approved creams application times
Cream name | Blood test | Cannula | Number of tubes allowed (max) |
---|---|---|---|
for children over 1 month |
30 mins | 40 mins |
1 tube under 5 years 5 tubes over 5 years |
for children over 1 month |
30 mins | 60 mins |
1g tube under 1 year Up to 2.5g over 1 year |
for children over 3 months |
60 mins | 60 mins |
1 tube under 5 years 2 tubes over 5 years |
Where and how to apply the cream
- Apply a pea-sized amount of cream to the back of both hands and inside of the elbow in the crease. DO NOT RUB IN.
- Cover with the dressing supplied. If you do not have a dressing, wrap 3 layers of cling film around the areas, ensure the cream is covered.
- See table above for the suggested time the cream needs to be in place. Please do this before coming to the hospital as it will delay other patients if applied at appointment time, and you may be asked to re-book.
- After the suggested application time, your nurse will remove the dressing and cream and will locate the best spot to take blood or insert cannula.
- Cream should not be left on for longer that the stated time as this can cause irritation and will have no benefit to the procedure.
- The areas will remain numb for up to 4 hours.
