Patient's question:
.5 Condition Description: My son is 6.5 years old and has cryptorchidism. The doctor at the hospital ordered a bone age test, which showed a bone age of 3 years. At the endocrinology department, his trace elements were normal, and his thyroid hormones (TT3, TT4, FT3, FT4, TSH) were all within the normal range. However, his serum growth hormone was only 0.4 (Newborn: 7.8-66.2, Adolescent: 1.0-48.8, Middle-Aged: 0-11.6). The nurse who delivered the report mentioned that there is still one insulin-like growth factor report pending. His height is 1.22 meters, and his weight is 31 kg, which is slightly overweight.History of Treatment and Effect: Is there a connection between cryptorchidism and growth hormone?
What kind of help do you expect:
Doctor's answer:
Hello, the reference range for pediatric growth hormone is: 1.00-5.00 ng/m.Guidance: However, growth hormone is secreted in pulses within the human body. Checking growth hormone once is generally not meaningful. It is recommended to perform a growth hormone stimulation test to observe the peak value. If the peak value is greater than 10, it indicates normal levels. If it is between 5 and 10, it suggests partial deficiency. If it is less than 5, it indicates complete deficiency.
Growth hormone is a DNA recombinant human growth hormone with the same effects as human growth hormone. It can promote the growth of bones, internal organs, and the whole body, enhance protein synthesis, influence fat and mineral metabolism, and plays a key role in human growth and development. Normal levels for boys should be 0.09-1.95, and for girls, 0.08-3.10.
