Internal Medicine - Endocrinology
In brief: IGF-1, MRI, others
A screening test is igf-1 (or insulin-like growth factor).
This test is more reliable than growth hormone (gh) because gh is released in pulses, so that a one-time measurement of gh doesn't mean much. If the igf-1 is high, further tests may include a test where glucose is given & gh check to see if if suppresses (normal) or stays high (acromegaly) and MRI is done to check for pituitary tumor.
