Product Name: Estradiol detection kit（Magnetic Solid Phase Chemiluminescent Immunoassay） Packaging: 24 T/KIT What is being tested? Estrogens are a group of steroids that are responsible for the development and function of reproductive organs and the formation of secondary sex characteristics in women. Along with another hormone, progesterone, they help regulate the menstrual cycle, are involved in the growth of breasts and the uterus, and help maintain a healthy pregnancy. Though considered the main sex hormones for women, they are also found in men and play a role in bone metabolism and growth in both sexes. Estrogen tests measure one of three components: estrone (E1), estradiol (E2), or estriol (E3) in the blood or urine. Estrone (E1) is directly converted from androstenedione (from the adrenal gland) or indirectly from other androgens. E1 can also be produced by the ovaries and placenta, testicles, and adipose (fat) tissues. E2 and E1 can be converted into each other as needed. E1 is the primary estrogen in men and in post-menopausal women. Estradiol (E2) is primarily produced in the ovaries under stimulation of FSH and LH in pre-menopausal women and in the testicles in men. E2 is converted from E1 in post-menopausal women. It is the most potent estrogen and the one that is present in the highest concentration in non-pregnant, pre-menopausal women. E2 levels vary depending on a woman’s age and reproductive status. They are a good marker of ovarian function. Estriol (E3) is produced by the placenta, with concentrations rising throughout a woman’s pregnancy. Increasing levels are an indication of the health of the pregnancy and developing baby.
