Bilirubin (Total, Direct and Indirect)
Understanding Bilirubin (Total, Direct and Indirect)
What is Bilirubin (Total, Direct and Indirect)?
A kidney, ureter, and bladder (KUB) X-ray helps to visualize the organs of urinary and gastrointestinal systems. It is performed to determine an intestinal blockage, foreign objects in the stomach, tumors, kidney stones and gallstones. It can also provide information regarding the size, shape, and position of the kidneys, ureters, and bladder. This X-ray is advised to people complaining of persistent or acute abdominal pain.
A KUB X-ray is primary evaluation of the urinary tract before performing any other diagnostic procedures.
What is Bilirubin (Total, Direct and Indirect) used for?
The Bilirubin (Total, Direct and Indirect) test is done in case of signs and symptoms of:
-
Liver damage
-
Liver disease
-
Bile duct blockage
-
Hemolytic anemia
-
Liver-related metabolic problems
-
Jaundice in newborns
Interpreting Bilirubin (Total, Direct and Indirect) results
Interpretations
The normal values of total bilirubin may range from 0.30 mg/dL to 1.20 mg.dL.
Reference range may vary from lab to lab*
- Increased total bilirubin which is mainly unconjugated may be due to hemolytic anemia, transfusion reactions
- Increased total bilirubin which is mainly conjugated may be due to viral hepatitis, drug reactions, alcoholic liver disease, gall stones or any obstruction in the bile ducts
- Low levels of bilirubin are usually not a cause for concern and therefore not monitored.
