Bilirubin is a protein and natural by-product of red blood cell breakdown. Measures amount of bilirubin formed in the liver to become water soluble.
1.0 mL serum (0.5 mL minimum) collected in serum separator tube (SST/Tiger Top)
Refrigerated (ship on frozen cold packs)
Refrigerated: 7 days
- Normal: 0.0-0.3 mg/dL
- High: >0.3 mg/dL
- If direct bilirubin is elevated more than total bilirubin, there typically is a problem with decreased elimination of bilirubin by the liver cells.
- Elevated serum levels could indicate liver diseases such as hepatitis, cirrhosis, neoplasm or gall bladder disease.
- Low levels are generally not a concern and are not monitored.
- The course of treatment is dependent on the cause of the jaundice. The determination of direct as well as total bilirubin is used in differentiating certain types of jaundice.
