Bilirubin, Total, Serum or Plasma
Also known as: BILIT
Use
This test is used to assess and monitor liver disorders, hemolytic anemia, and neonatal jaundice. Bilirubin is a yellow compound that occurs in the normal catabolic pathway that breaks down heme in vertebrates. It is processed by the liver, and its levels are used to evaluate liver function and the presence of diseases such as jaundice.
Special Instructions
Protect the specimen from light during collection, storage, and shipment to ensure accuracy. Use an ARUP amber transport tube for serum or plasma samples.
Limitations
The measurement is influenced by patient condition and external factors affecting the bilirubin levels, such as hemolysis, exposure to light, and improper handling of specimens. False elevations might occur if the specimen is not properly protected from light.
