Order LH Levels Blood Test | Luteinizing HormoneLuteinizing hormone (LH) is a glycoprotein hormone produced by the anterior pituitary gland. It plays a central role in reproductive function, acting on the gonads to drive ovulation in women and testosterone production in men. The LH Levels Blood Test measures the concentration of LH in the bloodstream, offering a direct view of pituitary signaling and gonadal feedback.
About LH Levels Blood Test | Luteinizing Hormone in Normal
The LH Levels Blood Test quantifies luteinizing hormone in serum, providing information about the hypothalamic-pituitary-gonadal axis.
In women, LH surges mid-cycle to trigger ovulation, and its levels shift across the menstrual cycle. In men, LH stimulates Leydig cells in the testes to produce testosterone. Because LH is released in pulses, a single measurement reflects one point in time rather than a continuous average.
Clinicians order LH testing to evaluate menstrual irregularities, suspected pituitary or hypothalamic disorders, delayed or precocious puberty, and fertility concerns. In men, it is often paired with follicle-stimulating hormone (FSH) and testosterone to assess testicular function.
Results are interpreted alongside FSH, estradiol or testosterone, and clinical context. Reference ranges vary by sex, age, and menstrual cycle phase, so the laboratory's own range is the appropriate standard for comparison.
