Question
What is the normal range of progesterone levels during an ultrasound examination for girls with precocious puberty?
Answer
In pediatric hormone testing, since normal children have not yet entered the stage of gonadal development, there are no standard values set. Generally, children’s hormone levels should be consistent with those of individuals who have not yet entered puberty, which is to say, low levels. Regarding jaundice issues, it may be physiological jaundice, with symptoms typically appearing 2 to 3 days after birth. Mild cases may only result in yellowing of the face and neck, while severe cases may involve the entire body, including the eyes and urine. Symptoms usually resolve within a week, and symptoms in premature infants may persist for a longer period. It is recommended to use blue light therapy, which can be effective for some cases.
