Quantitative Sensory Testing

Quantitative Sensory Testing (often called ’QST‘) allows us to measure changes in sensitivity to different types of sensations that can include temperature, touch or pressure. This information sheet from Great Ormond Street Hospital (GOSH) explains quantitative sensory testing for chronic pain and what to expect.

Colonic transit (pellet) study

A colonic transit study is a test that shows how quickly food passes through the digestive system. This may also be called a pellet study.  It starts when you give your child some pellets to swallow on three consecutive days. On the fourth day, they will need to come into hospital for an x-ray. If there are some pellets seen on this x-ray you might be asked to return for a second x-ray on day 6. This information sheet from Great Ormond Street Hospital (GOSH) explains about the transit study test and what to expect when your child has one.
