The precocious puberty stimulation test, also known as the luteinizing hormone-releasing hormone stimulation test. The method of examination involves administering an intravenous injection of gonadotropin-releasing hormone, followed by taking blood samples before the injection, and at 30, 60, 90, and 120 minutes after the injection. Serum levels of luteinizing hormone and follicle-stimulating hormone are measured to assess their peak values. This can diagnose whether the gonadal axis has been activated and is a reliable method for diagnosing precocious puberty.
