Figure 1From: Cross-reactivity of steroid hormone immunoassays: clinical significance and two-dimensional molecular similarity prediction Illustration of two-dimensional similarity to cortisol. The figure depicts chemical structures of cortisol, 6-methylprednisolone, 21-deoxycortisol, 17α-hydroxyprogesterone, boldenone, and mesterolone. Below each compound is the two-dimensional similarity to cortisol and the degree of cross-reactivity to the Roche Elecsys Cortisol immunoassay.Back to article page
