All appointments for blood tests MUST be pre-booked. Please do not attend any of our departments without an appointment as you will be turned away. Please note, Morriston Hospital has the fewest number of appointment slots and therefore the longest wait.

General information 

Blood tests, sometimes referred to as phlebotomy, have a wide range of uses and are one of the most common types of medical tests.

A blood test can be used to assess your general state of health, check if you have an infection, see how well certain organs such as the liver and kidneys are working and screen for certain genetic conditions.

The quickest and easiest way to book is by using the link above to the online booking page.
