The color tube for bilirubin direct is usually a green or dark green tube.
The tube used for bilirubin testing is typically a brown or amber-colored tube. This color is chosen to help protect the sample from light exposure, as bilirubin is light-sensitive.
You could use a Red/Gray SST tube, or you could use a Green sodium heparin tube.
A green or dark green tube is typically used for collecting blood samples for bilirubin testing. These tubes contain heparin as an anticoagulant.
A test tube used for bilirubin testing is typically amber-colored. This color helps protect the sample from light exposure, which can break down the bilirubin molecules and affect the test results.

Dead hepatocytes release direct bilirubin in circulation
A bilirubin total test typically requires a serum separator tube (SST), which is often gold or yellow in color. Some laboratories may also accept a green tube, which contains heparin as an anticoagulant. It's important to follow specific laboratory guidelines for the appropriate tube type. Always confirm with the testing facility for their requirements.
Serum bilirubin is primarily categorized into three types: direct (conjugated) bilirubin, indirect (unconjugated) bilirubin, and total bilirubin. Direct bilirubin is water-soluble and occurs after the liver processes bilirubin, while indirect bilirubin is fat-soluble and represents bilirubin that has not yet been conjugated by the liver. Total bilirubin is the sum of both direct and indirect bilirubin levels in the blood, often measured to assess liver function and diagnose various medical conditions.
For testing bilirubin, a red stopper tube is typically used to indicate the presence of clot activator or gel separator. Additionally, no additives are required for testing bilirubin levels in serum or plasma samples.
I can't remember the tube color (probably speckled or red for serum after clotting and centrifugation) but when I worked in a medical laboratory (until 2001) the key thing was to protect the specimen from light by wrapping the tube in aluminum foil!
The letters used to represent bilirubin count on a blood test are usually "T Bili" for total bilirubin and "D Bili" for direct bilirubin. Total bilirubin includes both direct and indirect bilirubin, while direct bilirubin specifically measures the amount that is conjugated and ready to be cleared by the liver.
In hepatic jaundice, direct bilirubin levels increase due to impaired liver function, which affects the liver's ability to conjugate and excrete bilirubin. When liver cells are damaged or inflamed, such as in hepatitis or cirrhosis, they may not effectively process unconjugated bilirubin into its conjugated form. Consequently, both direct (conjugated) and indirect (unconjugated) bilirubin can accumulate in the bloodstream, leading to jaundice. The increase in direct bilirubin specifically indicates that the liver is attempting to process bilirubin but is unable to eliminate it adequately.
