Description

Urobilinogen is a key tetrapyrrole compound and a major intermediate in the heme catabolic pathway. Its significance lies in its role as a diagnostic biomarker for liver function and hemolytic disorders, making it a critical reagent for clinical and research applications. This high-purity compound is essential for manufacturers of in-vitro diagnostic (IVD) kits, clinical laboratories, and biochemical research institutions focused on hepatobiliary and hematological studies.

Application

• Clinical Diagnostics: Primary calibrator and control material in enzymatic and chemical assays for the quantitative determination of urobilinogen in urine, a key indicator for liver function and hemolytic anemia.
• IVD Kit Manufacturing: A critical raw material for the production of reagent strips, automated analyzer reagents, and ELISA kits designed for urinalysis and liver panel tests.
• Biochemical Research: Used as a standard in studies investigating bilirubin metabolism, jaundice pathophysiology, and the enterohepatic circulation of bile pigments.
• Pharmaceutical Development: Employed in research for drug metabolism and toxicity studies related to hepatic function and bile acid pathways.
• Quality Control Laboratories: Serves as a reference standard for method validation and quality assurance in clinical and contract testing laboratories.
