Evaluating the sensitivity and specificity of the UK and Dutch growth referral criteria in predicting the diagnosis of pathological short stature.

In isolation, the UK auxological referral thresholds have limited sensitivity and specificity for pathological short stature. The combination of HtSDS and Ht-THSDS improved the sensitivity of UK criteria to detect pathology from 41% to 68%. Attention to the child's genetic height potential prior to referral can prevent unnecessary assessments.
