The clinical importance of urinalysis has been well documented as a useful tool in aiding with the diagnosis of various medical conditions. Urinalysis test strips and urine chemistry analyzers are now ubiquitous devices in physician's offices and medical labs alike. However, as routine as urinalysis has become today, the use of urine confirmatory tests (such as confirming the presence of urine bilirubin) remains inconsistent in the current laboratory testing practice.
Currently, there is no quantitative urine bilirubin test method on the market. The only way to rule out urine-strip false-positive bilirubin results is with a confirmatory assay such as Ictotest reagent tablets.
