A 6-year-old boy presents to his pediatrician for a routine physical examination. His mother reports no problems over the past year except that he seems to be shorter than the other boys in his class. His mother is 163 cm (5'4") tall and experienced menarche at age 12 years, and his father is 178 cm (5'10") tall and went through puberty at approximately age 14 years. On his growth curve, the boy’s height was at the 10th percentile at birth, at the sixth percentile by age 3 years, and at the third percentile now. His weight is currently at the 25th percentile. Which of the following is most important in this patient’s evaluation?
(A) Chromosomal analysis
(B) Colonoscopy
(C) Growth hormone level
(D) Insulin-like growth factor-1 level
(E) No further evaluation is necessary
