PRL Rapid Quantitative Test

Prolactin is the hormone that tells the body to make breast milk when a person is pregnant or breast-feeding. Production of prolactin takes place in the pituitary gland. For those who are not pregnant or breast-feeding, there are only low levels of prolactin in the body.
Product Detail
PRL is a single chain protein, secreted by antepituitary basophil, which consist of 199 amino acids with molecular weight of 23kDa. PRL has the function of promoting proliferation of mammary gland and lactation. The level of PRL rises up during pregnancy, reaches its peak when delivery, then declines after lactication. Lactication with newborn will bring about an increase of the concentration. The concentration of PRL in blood rises up when there is pituitary tumor occurring, such as prolactin-producing tumor, acromegalia, primary hypothyroidism, cancer, hypothalamus tumor[1-3].

Biotime FSH rapid fluorescence immunoassay test
FSH Rapid Quantitative Test
FSH is synthesized and secreted by the gonadotropic cells of the anterior pituitary gland, and regulates the development, growth, pubertal maturation, and reproductive processes of the body. FSH and luteinizing hormone (LH) work together in the reproductive system.
Biotime LH Rapid Quantitative Test
LH Rapid Quantitative Test
Luteinizing hormone is a hormone produced by gonadotropic cells in the anterior pituitary gland. In females, an acute rise of LH ("LH surge") triggers ovulation and development of the corpus luteum. In males, where LH had also been called interstitial cell‒stimulating hormone (ICSH), it stimulates Leydig cell production of testosterone. It acts synergistically with follicle-stimulating hormone (FSH).
Biotime estradiol Rapid Quantitative Test
E2 Rapid Quantitative Test
Estradiol (E2), is an estrogen steroid hormone and the major female sex hormone. It is involved in the regulation of the estrous and menstrual female reproductive cycles. Estradiol is responsible for developing female secondary sexual characteristics and is important in the development and maintenance of female reproductive tissues.
