There are a high number of potentially interfering compounds present in serum which are often encountered during methods development for quantitating steroids. Many of these interferences are eliminated by utilizing a synthetic matrix. It is advantageous to have a steroid control in a synthetic serum matrix to verify calibration curves and a steroid serum control.
