This isolation serum growth hormone (GH) test measures the level of growth hormone in the blood, which is produced by the pituitary gland and plays a key role in growth, metabolism, and tissue repair. It is used to help evaluate conditions like growth hormone deficiency or excess GH.
This test is intended to be performed calorie-fasting is usually required for this test, and it is typically done in the morning, as GH levels fluctuate throughout the day. However, a single GH measurement may not be reliable due to its pulsatile secretion, so other tests, like IGF-1 or GH stimulation/suppression tests, are often done for more accurate diagnosis.
