Objective: Immunoassays of steroids are still used in the diagnosis and biochemical monitoring of patients with congenital adrenal hyperplasia due to 21-hydroxylase deficiency (21 OHD). However, high levels of steroid intermediates can promote cross-reactivity between steroids giving rise to falsely elevated levels.Design: Fifty-nine patients with classic 21OHD (38 women) were studied. Blood samples were collected in the morning after overnight medicatio...
