Overview:
LH is one of the gonadotropins of the anterior pituitary gland that works with FSH to induce ovulation of mature follicles and secretion of estrogen by the ovary. LH is also involved with the formation of the corpus luteum. In the male LH stimulates the development of the interstitial cells of the testes and their secretion of testosterone.
Methodology
Immunoassay – Sandwich principle
- LH is used to assess for dysfunctions within the hypothalamic-pituitary-gonadal system1-4
- LH in conjunction with FSH is utilized for the following indications:1-4
- Menopausal syndrome
- Polycystic ovarian syndrome (PCOS)
- Testosterone deficiency
- Amenorrhea (causes)
- Congenital diseases with chromosomal aberrations
- High doses of biotin (> 5 mg/day) may interfere with assay results. Patient assumed to be refraining from biotin supplementation for at least 3 days prior to blood draw.
