LHRH stimulation test
Also written as: LHRH — Luteinizing Hormone-Releasing Hormone stimulation test
Diagnostic test measuring luteinizing hormone response to synthetic luteinizing hormone-releasing hormone to assess pubertal status.
Full Definition
A diagnostic procedure where synthetic luteinizing hormone-releasing hormone (LHRH) is administered, and blood samples are taken to measure the resulting LH and FSH response. This test helps distinguish between central and peripheral causes of pubertal disorders and confirms pubertal onset. The magnitude of LH response indicates whether the hypothalamic-pituitary-gonadal axis has been activated. It is particularly useful in evaluating children with ambiguous pubertal timing or suspected central precocious puberty.
Usage
Usage note: Always specify whether referring to the test procedure or the results when editing clinical documentation.
