Abstract
A method for direct serum assay of steroid hormones wherein the competition from binding protein, having an affinity for complexing with the steroid hormones, is significantly eliminated by adding to the serum an artificial compound which has a greater or equal affinity for the binding protein than do the steroid hormones, and which is not immuno-reactive with the steroid hormones. Because the compound is artificial, it is non-contaminating. Levonorgestrel and norethindrone as such compounds are disclosed.
