A competitive protein-binding method was used to determine serum thyroxine concentration throughout childhood, adolescence, and in young adults. The values showed a gradual decrease as the child became older and reached adult levels by the time of adolescence. The range (mean +/- 2 SD mug/100 ml) for cord serum was 8.8-14.8; for 4 weeks to 11 years, 6.5-13.9; for 11 to 17 years, 5.4-12.2, and for young adults 6.0-11.2.
采用竞争性蛋白结合法测定儿童期、青春期及青年期的血清甲状腺素浓度。结果显示,随着儿童年龄增长,该值逐渐下降,到青春期时达到成人水平。脐血血清的范围(均值±2标准差μg/100 ml)为8.8 - 14.8;4周龄至11岁为6.5 - 13.9;11至17岁为5.4 - 12.2;青年人为6.0 - 11.2。
