A radioimmunoassay (RIA) technique was developed for the purpose of determining the sex of an individual by measuring the steroids testosterone (T), progesterone (P), and estradiol-17 beta (E2) in dried bloodstains. The steroid values from a single bloodstain are reported as ratios T/P, T/E2, and P/E2. The results reported include data on the validation of this technique, results of analysis of 146 duplicate bloodstains representing 112 samples from females and 34 samples from males as controls, and results of analysis of 114 duplicate bloodstains representing 60 from females and 54 from males that were submitted as a blind study to test the accuracy of this RIA technique in determining the sex of an individual from a dried bloodstain.
为通过测量干血斑中的睾酮（T）、孕酮（P）和雌二醇 - 17β（E2）这几种类固醇来确定个体性别，开发了一种放射免疫分析（RIA）技术。单个血斑的类固醇值以T/P、T/E2和P/E2的比率形式报告。报告的结果包括该技术的验证数据、对146对重复血斑的分析结果（这些血斑代表112份女性样本和34份男性样本作为对照），以及对114对重复血斑的分析结果（这些血斑代表60份女性样本和54份男性样本，作为一项盲法研究提交，以测试这种RIA技术从干血斑确定个体性别的准确性）。
