| Abstract: | Abstract Three procedure for 17-ketosteroids are compared: The method of Callow et al., the method of Drekter et al. and the method of Corker et al. Good correlation has been found between results obtained by the methods of Callow and Corker. Analyses of single analytical steps showed that Drekter's method gives in some cases too high results because non-specific chromogens are included when readings are taken only at 520 nm. Of these three procedures that of Corker et al. is proposed as the method of choice. |
