22248 Bilirubin, Direct Only

Bilirubin, Direct Only
Test Code: DBIL
Synonyms/Keywords
DBIL, Conjugated Bilirubin​, Fractionated Bilirubin
Useful For
Direct bilirubin measurements are used in the diagnosis and treatment of liver, hemolytic, hematological, and metabolic disorders, including hepatitis and gall bladder block.​
Specimen Requirements
Fasting Required Specimen Type Preferred Container/Tube Acceptable Container/Tube Specimen Volume Specimen Minimum Volume
(allows for 1 repeat)		 Pediatric Minimum Volume
(no repeat)
No​ Plasma​/Serum Lithium-heparin Plasma Separator (PST), Serum Separator Tube (SST)​ Lithium or Sodium-heparin Green Top (GTT), Red Top Tube(RTT)
 1 mL​ 0.3 mL​ 0.3 mL serum or plasma from 0.6 mL whole blood
Collection Processing Instructions
Bilirubin is light sensitive.  Protect samples from light.
Samples collected in a SST or RTT must be removed from cells within one hour for storage or transport.
DBIL can only be U-Haved/add-on from a previously collected sample if requested within 24 hours of the original collection, or if the sample has been protected from light.
