Two newly developed photometric assays for the estimation of faecal chymotrypsin were studied in comparison with the established titrimetric method in 46 patients and 8 healthy volunteers, who had undergone a secretin-pancreozymin test for diagnostic purposes. The correlation between the two photometric methods and the titrimetric method was good (r = 0.90 and r = 0.91), revealing similar diagnostic sensitivity and specificity. As both photometric methods are less time-consuming and may be performed using a standard laboratory equipment, they offer a good alternative to the established titrimetric method for faecal chymotrypsin estimation.
在46例患者和8名健康志愿者中，研究了两种新开发的用于评估粪便糜蛋白酶的光度测定法，并与既定的滴定法进行比较。这些患者和志愿者因诊断目的接受了促胰液素-胰酶泌素试验。两种光度测定法与滴定法之间的相关性良好（r = 0.90和r = 0.91），显示出相似的诊断敏感性和特异性。由于两种光度测定法耗时较少，且可使用标准实验室设备进行操作，因此它们为既定的粪便糜蛋白酶滴定法评估提供了一个很好的替代方法。
