In this rapid, cost-effective, enzyme-linked immunosorbent assay for 17 alpha-hydroxyprogesterone (17-OHP) eluted from dried blood spotted on filter paper, second antibody is coated onto the microwell plate and horseradish peroxidase (EC 1.11.1.7) is the label enzyme. Antiserum to 17-OHP was prepared by using 4-(2-carboxymethylthio)-17-OHP-bovine serum albumin conjugate as immunogen. Enzyme conjugate was prepared from 4-(2-carboxymethylthio)-17-OHP and peroxidase. The blood spots are assayed in the microwells without extraction or centrifugation steps. The detection limit of the assay is 1 microgram/L, equivalent to 3.5 pg (10.6 fmol) per disc. Intra- and interassay CVs at two steroid concentrations (7.38 and 22.79 micrograms/L) ranged from 3.74 to 11.90% (n = 5), and 9.49 and 9.83% (n = 5), respectively. Results correlated well (r = 0.91) with those of a fluorescence enzyme immunoassay. The sensitivity, specificity, and precision of this method make it potentially useful in the mass screening of neonates for congenital adrenal hyperplasia.
