Which test is known as a confirmatory test for bilirubin?

The test recognized as a confirmatory test for bilirubin is Ictotest. This test is specifically designed to detect the presence of bilirubin in urine with a high degree of sensitivity and specificity. The Ictotest uses a tablet that reacts with bilirubin, producing a color change that can indicate the concentration of bilirubin present. Because of its distinct methodology and effectiveness, it has become a standard confirmatory test for evaluating conditions related to bilirubin, such as liver disease or hemolytic disorders.

In contrast, Acetest is primarily used to detect ketones, Clinitest is used for detecting reducing substances such as glucose in urine, and aminocentesis is a procedure to obtain amniotic fluid for prenatal testing. These tests do not evaluate bilirubin directly, which is why they do not serve as confirmatory tests for this particular substance.
