University Hospital Southampton NHS Foundation Trust

Children's blood tests

We offer a blood test service for children up to the age of 18 in our butterfly room (16 and 17 year olds may visit the adult blood test service instead if they prefer).

If the blood test has been requested by your child’s GP or CAMHS then you must make an appointment. Please call 023 8120 2024 (lines are open 8.30am to 4.30pm, Monday to Friday).

If the blood test has been requested by your child’s nurse or doctor from the hospital, or a community paediatrician, you can use our walk-in service between the hours of 8.30am to 5.00pm, Monday to Friday (or 8.15am for a fasting blood test).

Please encourage your child to drink plenty of fluids before their blood test (for fasting blood tests offer water only). We can offer options to numb your child's skin before their blood test, to reduce any pain or discomfort.

You can find out more about the process of the blood test, and watch a video about preparing your child, here.

We often see children with complex or additional needs, but if you're concerned that your child may need additional support and would like to speak to us in advance, please call us on 023 8120 4075.
