What is this test?
This test measures the amount of luteinizing hormone in the blood. (LH) is a hormone associated with reproduction? Its stimulation of either ovary or testicles results in the release of an egg from the ovary (ovulation) in women or testosterone production in men.
 
Sample required
Blood.
 
Patient preparation
Early morning samples are preferred. A woman’s sample should be collected at specific times during her menstrual cycle. Inform the doctor if you are on any medications, or have any allergies or underlying medical conditions before this test.
 
Turn-around time (How long does it take?)
5 Hours.
 
Basis of the Test
LH is produced by the pituitary gland. In women of childbearing age, several hormones (LH, follicle-stimulating hormone (FSH), estrogen and progesterone) rise and fall in a specific sequence during each menstrual cycle. In men, LH stimulates Leydig cells in the testicles to produce testosterone. In infants and children, LH levels rise shortly after birth and then fall to very low levels. Results of an LH test are typically considered with results of other hormone tests, such as FSH, estrogens, and/or testosterone.
