Question

Quizplus · Accepted Answer

Biliary duct obstruction can cause an increase in bilirubin levels, which can be detected by reagent strip tests as "++" (or sometimes "2+", depending on the strip manufacturer). However, the obstruction can also cause a decrease in urobilinogen levels, which may be detected as a lower-than-normal value (such as 0.1 EU). Choices A and C only show one abnormal result and do not fit the expected pattern for biliary duct obstruction. Choice D shows an abnormal increase in both bilirubin and urobilinogen, which is not typical of biliary duct obstruction.
