Danazol therapy can cause false elevations in serum testosterone due to cross-reactivity, leading to apparent virilization which resolves upon drug discontinuation.

Abstract

Several steroid radioimmunoassay kits, particularly testosterone, cross-react with danazol, producing false elevations of serum steroid levels. A patient taking danazol simultaneously developed signs of virilization and an apparent 15-fold elevation in her serum testosterone. Discontinuation of danazol resulted in a prompt return to physical and biochemical normality.
