Abstract

You are seeing an 11-year-old boy in a general paediatric clinic referred with short stature. His height is below the 0.4th centile. The mid-parental height is on 50th centile. Baseline investigations, including renal and liver function, coeliac screen and thyroid function tests are normal. You have a suspicion of growth hormone deficiency. Should you check an insulin-like growth factor-1 level or proceed with a growth hormone provocation test? The current paper will aim to give an overview of these tests and factors to consider when interpreting the results.
