Bromocriptine (BCT) inhibition of PRL test

Bromocriptine (BCT) inhibition of the PRL test is carried out by the following principle: BCT is a dopamine drug that acts on the dopamine receptor of PRL cells and inhibits the secretion of PRL. Method 1, BCT 2.5mg orally. 2. Blood samples were taken at 0, 0.5, 1, 2, 4, and 6 hours to determine PRL. Analysis: 1, simple and functional lactation is mostly a normal inhibition reaction. 2, PRL tumor, anterior pituitary dysfunction is mostly negative inhibition reaction. Basic Information Specialist classification: growth and development check classification: endocrine examination Applicable gender: whether men and women apply fasting: not fasting Tips: Pay attention to the normal diet, pay attention to normal work and rest, and prevent endocrine disorders. Normal value Normal value: normal person inhibition rate >50%, peak value appears in 60-120 minutes, and lasts 4 hours or more. Clinical significance 1. Simple and functional lactation is mostly a normal inhibitory response. 2, PRL tumor, anterior pituitary dysfunction is mostly negative inhibition reaction. Abnormal results: A. PRL tumor 1. Female PRL tumors: mostly microadenomas, found in young people aged 20 to 30. The typical symptom is amenorrhea-milk-infertility triad. Secondary amenorrhea is more common, accounting for about 90%. Milk spill is the main manifestation of this disease, mostly for touch lactation, accounting for 50% to 90%. Sexual dysfunction accounts for about 60%, complaining of decreased or absent libido, loss of sex, lack of orgasm, and sputum pain. 2. Male PRL tumor: Male prolactinoma is generally diagnosed when it is diagnosed, often developing on the saddle, but relatively rare. The main symptoms of sexual dysfunction, accounting for about 83%, can be complete or partial. If the degree of libido declines, impotence, male infertility and the number of sperm decreased. Second, anterior pituitary dysfunction Partial pituitary dysfunction is more common than all pituitary dysfunction. Lack of prolactin (PRL) secretion is less common, except for pituitary necrosis after delivery. Hyperprolactinemia may be due to tumors (such as prolactin tumors), but more commonly due to dysfunction of the hypothalamus, increased secretion of PRL in normal glands. People who need to be examined: amenorrhea-milk-infertility, loss of libido, impotence, male infertility and decreased sperm count, and symptoms of prolactin (PRL) secretion caused by anterior pituitary dysfunction patient. High results may be diseases: impotence, male infertility, hyperprolactinemia, hyperprolactinemia precautions Forbidden before examination: pay attention to normal diet, pay attention to normal work and rest, and prevent endocrine disorders. Requirements for inspection: Actively cooperate with the doctor's request. Inspection process method: 1, BCT2.5mg orally. 2. Blood samples were taken at 0, 0.5, 1, 2, 4, and 6 hours to determine PRL. analysis: 1. Simple and functional lactation is mostly a normal inhibitory response. 2, PRL tumor, anterior pituitary dysfunction is mostly negative inhibition reaction. Not suitable for the crowd Inappropriate crowd: temporarily unknown. Adverse reactions and risks No obvious complications and harms.
