[Diagnostic value of the lipoprotein-X determination (author's transl)]

LP-X was investigated in the serum of 221 patients with and without cholestasis. The diagnostic sensitivity and the diagnostic specificity of the test were 0.9 and 0.88, respectively. When this test is used on a non-selected collective, however, the predictive value of the positive test is very low, whereas negative results have a high diagnostic value. Thus, in practice, LP-X is more suitable for the exclusion, rather than the detection of cholestasis.
