Follicle-stimulating Hormone (FSH), Pediatric (Endocrine Sciences)
Use
The Follicle-stimulating Hormone (FSH) test is used in pediatric endocrinology to evaluate the functioning of the hypothalamus-pituitary-gonadal axis in children. It helps in diagnosing conditions related to abnormal development of secondary sexual characteristics, such as precocious or delayed puberty. FSH levels can provide insight into disorders of pituitary or gonadal function and assist in determining appropriate therapeutic pathways for pediatric patients.
Special Instructions
Serum or plasma must be separated from cells within 45 minutes of venipuncture and sent in a plastic transport tube. Separate frozen specimens are required for each test requested to avoid delays. Ensure proper freezing to maintain sample integrity.
Limitations
This FSH test has technical constraints impacted by improper sample handling that can affect hormone stability. Delay in processing or improper storage conditions can lead to inaccurate results. The test does not differentiate between various causes of pituitary or gonadal dysfunction without correlation with clinical findings and additional diagnostic procedures.
