Luteinizing Hormone Stimulation Test
Specialised GnRH/Leuprolide stimulation testing to evaluate central precocious puberty and hypothalamic-pituitary-gonadal maturation.
Understanding Your Child's Growth
The Luteinizing Hormone (LH) Stimulation Test, also known as the GnRH or LHRH stimulation test, evaluates the activation of the pituitary gland’s reproductive hormone axis.
Under the care of Dr. Smita Ramachandran, this test provides definitive differentiation between true central precocious puberty and benign pubertal variations.
When Is Evaluation or Testing Needed?
- Girls show breast development before age 8.
- Boys show testicular enlargement before age 9.
- Accelerated height velocity accompanied by advanced bone age is observed.
- Delayed puberty requires differentiation between constitutional delay and hypogonadotropic hypogonadism.
Early Attention Makes a Difference
Precise pubertal testing protects adult height potential and emotional well-being.
Guiding children through healthy, timely pubertal transitions.
What Does the Evaluation Involve?
- Baseline Sample: Measurement of baseline LH, FSH, estradiol, or testosterone.
- GnRH / Leuprolide Dose: Subcutaneous or intravenous administration of the stimulating peptide.
- Serial Sampling: Timed blood samples drawn at 30, 60, and 90 minutes.
- Definitive Diagnosis: A peak LH response over specific thresholds confirms central pubertal activation, guiding GnRH analogue therapy decisions.
