Blood Quest
Play the Blood Quest app for iPad and find out more about your blood and what happens during a blood test. Blood Quest is designed to inform, entertain and distract children and young people whilst having blood taken.
Blood Quest has been developed by specialists at Great Ormond Street Hospital (GOSH) to help children and young people prepare for blood tests and alleviate anxiety. Distraction, information and gaming have been shown to improve the patient experience of this procedure.
