Used in research settings to measure levels of sex hormone-binding globulin in human serum or plasma. This kit enables scientists to study hormonal imbalances related to conditions such as polycystic ovary syndrome (PCOS), hypogonadism, and infertility. It supports investigations into endocrine function, reproductive health, and metabolic disorders. Commonly applied in clinical research, epidemiological studies, and drug development where accurate quantification of SHBG is required. The assay helps assess bioavailability of sex hormones like testosterone and estradiol, providing insight into hormone regulation and related diseases.
