• Description :
• Testosterone is a steroid with a MW of 288.4 Dalton. The main sites of testosterone secretion are Leidig cells in interstitial tissue of testicles in men. In women testosterone is secreted in the adrenals and is controlled by luteinizing hormone. Testosterone stimulates development of male genital organs and formation of secondary sexual features. In males, Testosterone secretion undergoes circadian rhythms with maximal concentrations seen in the morning (6 am) and minimal in the evening (8 pm). In females, Testosterone secretion is regulated by menstrual cycle with maximal levels found in luteinic phase and during ovulation. Leidig cell tumors producing high levels of serum/plasma testosterone in young boys lead to development of "little Hercules" syndrome. Elevated testosterone level in women causes the clinical signs of masculinization. In men, decreased Testosterone levels may lead to female habitus or underdevelopment of male genital organs in boys. To differentiate between primary and secondary hypogonadism, Testostrerone should be assayed in conjunction with LH and FSH. PRINCIPLE OF THE TEST This test is based on competition enzyme immunoassay principle. Tested specimen is placed into the microwells coated by specific anti-Testosterone-antibodies simultaneously with conjugated Testosterone-peroxidase. Testosterone from the specimen competes with the conjugated antigen for coating antibodies. After washing procedure, the remaining enzymatic activity bound to the microwell surface is detected and quantified by addition of chromogen-substrate mixture, stop solution and photometry at 450 nm. Optical density in the microwell is inversely related to the quantity of specific antibodies in the specimen. Trademark: JD Model NO.: JE007 Company: Jei Daniel Biotech Corp.
