DiaSorin  is pleased to announce the launch of the new LIAISON® test for the measurement of SHBG (Sex Hormone-Binding Globulin) in human serum and plasma, available worldwide with the exception of the U.S. SGHB, which is produced in the liver, is involved in transport of sex steroids, such as dihydrotestosterone, testosterone and estradiol, in the blood stream. The combined measurement of SHBG and testosterone levels helps determining causes of infertility, decreased libido and erectile dysfunction in men, and diagnosing polycystic ovarian syndrome (PCOS) in women.
