Total Neutral 17-Ketosteroids

[摘要] The Masuda and Thuline method for measuring urinary neutral 17-ketosteroids has been modified by substituting polyethylene bottles and a mechanical shaker for separatory funnels and manual shaking, and by developing the color and reading it in the same test tube. Combining Zimmermann reagents before addition eliminates the necessity for frequently pipeting small volumes. The new method permits the analysis of 10 to 15 urines in a single operation without sacrificing accuracy or specificity.
