testosteronetestosterone assay, or testosteronetestosterone assay, is the main male hormone in mentestosterone assayThe normal reference value is important for physiological health. Testosterone levels in adolescent men are usually between 0.43 ngdl, while the normal range for adult men is 2601250ngdl. Women's testosterone levels are lower. Testosterone testing is generally performed within the range of 4100ngdl., which can help doctors.testosterone assayUnderstanding an individual's endocrine status is a test that is available in clinical diagnosis.
Testosterone is the androgen in the body and is secreted by men's testes or women's ovaries. If testosterone in the body is increased, it can be seen in idiopathic male precocious puberty familial male precocious puberty adrenocortical tumors testicular tumors feminized polycystic ovarian syndrome ovaries tumors pineal tumors idiopathic hirsutism hypothyroidism androgens or chorionic gonadotropin treatment moderate testosterone levels can be seen in men's testes.
Dihydrotestosterone measurement is an important test to assess the level of DHT hormone in the reproductive system. The following is the key information about the determination of DHT. Normal reference value for men is 103292 nanomoles per liter for women is 014076 nanomoles per liter. The significance of the determination of DHT to understand the physiological state. DHT plays a key role in the reproductive system, and its level can reflect an individual's physiological state. Diagnosis of diseases abnormal DHT levels may be associated with certain endocrine diseases.
The main purpose of male testosterone measurement is to understand the androgen level in men. Testosterone is the androgen secreted by Leydig cells in men's testes. It plays a very important role in judging the function of male gonadal axis. If male testosterone levels decrease, it usually indicates that male gonadal axis function is low. At this time, we must understand the specific reasons and adopt corresponding treatment according to the specific reasons. Otherwise, male testosterone will be in a low state for a long time, and the proportion of protein and fat synthesis in the body will be determined.
The content of testosterone propionate is mainly determined by high-performance liquid chromatography. The specific determination method is as follows: The experimental materials and condition fillers use octadecylsilane-bonded silica gel mobile phase methanol and water, and the ratio is 6535. The detection wavelength is set to 254nm. Theoretical plate number requirements are calculated based on the progesterone peak. The resolution requirement is that the resolution between the progesterone peak and the internal standard material peak must meet specific requirements. The preparation of the internal standard solution takes about 25.
The content of testosterone undecanoate is determined by high-performance liquid chromatography. The specific operation method is as follows. First, a system suitability test is carried out. Octadecylsilane-bonded silica gel is used as the filler, the mobile phase is acetonitrile, isopropanol and water ratio is 434314, and the flow rate is 15 ml per minute, and the detection wavelength is set to 254 nm. The number of theoretical plates should reach or exceed 4000 to ensure that the testosterone undecanoate peak and the internal standard material peak have a good separation effect.
