There are three diagnostic criteria for dwarfism as follows: First, height is more than 2 standard deviations below normal for the same age and sex. Second, the growth rate is less than 4 cm per year, and third, the bone age on X-ray is more than 2 years below the normal value for the same age and sex. Fourth, the growth hormone excitation test is abnormal, and the growth hormone peak in plasma is low. If the above are supported, other factors causing growth retardation should be excluded. The diagnosis can be made based on delayed growth or short stature and slow growth rate, lower bone age on X-ray than children of the same age, and too little growth hormone secretion in blood and urine.
