Detaljerad beskrivning
In vitro cell-based bioassays may be a technique to measure serum androgen or estrogen bioactivity. In this study investigators are collecting serum (and if possible, urine) samples from different cohorts of patients, before and/or after treatment.
The aim is to measure androgens, estrogens and SHBG as well as in vitro bioactivity with newly developed cell-based bioassays, and to compare different techniques to each other as well as to clinical endpoints available in the patient's Electronic Health Record.
