Expected Turnaround Time
Within 1 day
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Serum (preferred) or plasma

Red-top tube, gel-barrier tube, or green-top (lithium heparin) tube.
Separate serum or plasma from cells within 45 minutes of collection.
To screen for or monitor liver disorders or hemolytic anemia; to monitor neonatal jaundice.
When you have signs or symptoms of liver damage, liver disease, bile duct blockage, hemolytic anemia, or a liver-related metabolic problem, or if a newborn has jaundice.
In adults, a blood sample drawn from a vein in the arm; in newborns, a blood sample from a heelstick; non-invasive technology is available in some healthcare facilities that will measure bilirubin by using an instrument placed on the skin (transcutaneous bilirubin meter).
You may need to fast (nothing but water) for several hours before the test; fasting requirements vary by laboratory; ask your lab or healthcare provider for instructions.
