Case: In March, the baby had a cold and fever and went to the hospital for blood tests. She took the opportunity to check her growth and development. According to the doctor's arrangement, I did a bone age test and a growth factor test. It was found that the bone age was up to 3.5-4 years old, the weight was 52, the height was 106, the growth factor 1 value was low, and the vitamin AD deficiency was not calm at all. The doctor said that at present, it is stunted. At present, it is necessary to improve work and rest, adjust diet, and observe after half a year. If you don't grow well, you need drug intervention, because growth factors don't go up on their own, they have to secrete on their own.
Different ages have different meanings for bone age measurement, so when is it best to measure bone age?
Early in sexual development, bone age testing is done. Girls are around 8 years old and boys are around 10 years old. During this period, tests show that children enter puberty at a normal level and rate of development in order to ensure that the child's sexual development and height development can grow normally. It is recommended to have a bone age test done every six months or every year according to the characteristics of sexual development.
How can I tell if my child is deficient in growth hormone?
The index growth hormone stimulation test is performed in the morning when there is no exercise and on an empty stomach. Fasting begins the night before the test, and fasts are completed throughout the test. Two drug provocative tests (avoid false positives of 15% of one drug in the provocation test). Drugs include: insulin, clonidine, arginine, levodopa, etc. Choose two drugs, one that stimulates the release of growth hormone and one that inhibits the release of growth hormone. Route of administration: oral and intravenous. Oral and intravenous administration can reduce the likelihood of rapid onset of action by oral administration due to digestion and absorption.
D. Time and frequency of blood collection in the provocation test: blood collection is taken once before administration, the basic growth hormone value is determined, and the blood is collected 30, 60, 90 minutes after administration to determine the growth hormone value. e. Result judgment: Any GH peak ≥ 10ng/ml is normal; GH
Bone age is the age of the bones. Nutrition, genetics, the environment, and diseases all affect the normal development of bones. If you do not know the age of the child's bones, you cannot judge whether the child's current height is abnormal, nor can you judge what the child's future height will look like.
