C75-01-4 Vinyl chloride)(115-09-3 Methylmercury chloride) Neither the original std. nor conservative GMH confidence limits seem adequate for practical application. Moreover, the recent appearance of new confidence limits makes it difficult to know what to use. The GMH procedure employs Abbott's correction, which assumes that the response due to background is totally independent of the response due to added toxic substance. This is a difficult assumption to verify and, as indicated, even a slight departure has a great effect on the virtually safe dose ests.

The following 3 techniques were noninvasive: (1) grey scale ultrasonog. of the liver; (2) microvascular skin capillary assessment; and (3) urinary anal, of glycosaminoglycan (GAG) excretion. The 9th technique was the std. 99mTc-S colloid liver-spleen scan. The screening studies were performed on a randomly selected group of chem. workers. All 9 techniques were analyzed for their sensitivity and specificity as compared to results of the liver biopsy and biochem. blood test classification. Although all 9 screening techniques had a sensitivity and specificity sum >1, none were better than could be explained by chance or the use of the biased coin. Reclassification of the population into those with more severe biochem. abnormalities improved the sensitivity of all screening tests, but only the sensitivity and specificity sum for the GAG test was significant.
