Endocrine / Hormones
Also known as: lutropin, interstitial cell stimulating hormone, ICSH
No common urgent flag from this test alone. However, if you experience sudden, severe symptoms like unexplained fatigue, significant weight changes, or severe pain, seek immediate medical attention.
This test checks how much Luteinizing Hormone (LH) is in your blood or pee. LH is a chemical signal. Your pituitary gland makes it. LH is very important for growing up sexually and for having babies.
Your doctor orders this test to help figure out problems with getting pregnant. It also helps with periods that are not regular. It can also help with issues during puberty. This test can also find problems with your pituitary gland. It can check your ovaries or testicles too.
LH levels vary greatly depending on your age, sex, and where you are in your menstrual cycle if you are a woman. Reference ranges are approximate and can differ between laboratories. Your doctor will interpret your results based on your individual situation.
