LH EIA Test Kit An enzyme immunoassay (EIA) for the quantitative detection of LH (luteinizing hormone) in human serum. The LH EIA Test Kit is an enzyme immunoassay for in vitro quantitative determination of LH level in human serum. Luteinizing hormone (LH) weighs approximately 30,000 Daltons and is also called interstitial cellstimulating hormone or ICSH in men. LH like FSH, TSH and hCG is a glycoprotein consisting of two subunits (a and ß-chains). The a-chains consist of 89 amino acid residues while the ß-chains contain 129 amino acids. While the a-chains of all the glycoprotein hormones are very similar, the ß-chains carry the hormone-specific information.1,2 Determination of the concentration of LH is essential for the prediction of ovulation, in the evaluation of infertility, and the diagnosis of pituitary and gonadal disorders. The determination of the LH in conjunction with FSH is utilized for the following indications: congenital diseases with chromosome aberrations (e.g. Turner’s syndrome), polycystic ovaries (PCO), clarifying the causes of amenorrhea, menopausal syndrome and suspected leydig cell insufficiency.3 The LH EIA Test Kit is an immunoassay for the quantitative detection of the presence of LH in serum specimen. The test utilizes monoclonal antibodies to selectively detect LH in serum.
