Order LH Levels Blood Test | Luteinizing HormoneThe LH Levels Blood Test measures the concentration of luteinizing hormone in the bloodstream. Luteinizing hormone is a glycoprotein produced by the anterior pituitary gland, and it plays a central role in reproductive function for both women and men. Because LH works in concert with other hormones, its measurement is often interpreted alongside related tests rather than in isolation.
About LH Levels Blood Test | Luteinizing Hormone in Orange
Luteinizing hormone functions as a signaling molecule within the hypothalamic-pituitary-gonadal axis, the feedback system that governs reproductive hormone production.
In women, LH surges mid-cycle to trigger ovulation, and it supports the formation of the corpus luteum, which produces progesterone during the second half of the menstrual cycle. In men, LH stimulates Leydig cells in the testes to produce testosterone.
Because LH release follows a pulsatile pattern, a single measurement reflects one moment in a continuously fluctuating cycle. Clinicians therefore consider the timing of the sample, the person's age and sex, and the results of companion tests such as follicle-stimulating hormone, estradiol, or testosterone.
The test requires a blood draw, typically from a vein in the arm. Results are usually reported in international units per liter, though reference ranges vary by laboratory and by the individual's sex and reproductive stage. Preparation instructions should be followed as provided by the laboratory performing the collection.
