UPLOAD YOUR BLOOD TEST

Total Bilirubin (TBIL) measures the amount of bilirubin in your blood. Bilirubin is a yellow compound produced when red blood cells break down. It's processed by the liver and excreted in bile. This test helps assess liver function and can detect conditions like jaundice, hepatitis, or bile duct obstructions. Elevated levels may indicate liver disease, while low levels are generally not concerning. TBIL is crucial for evaluating overall liver health and identifying potential issues with bilirubin metabolism or excretion.

What do readings below 0.1 mg/dL for Total Bilirubin - TBIL mean?

A Total Bilirubin level below the normal range is generally not considered clinically significant. Low bilirubin levels are rarely a cause for concern and typically don’t indicate any specific medical condition. In some cases, it might be associated with:

  • Caffeine consumption
  • Certain medications
  • Vigorous exercise

However, persistently low levels should be discussed with a healthcare provider to rule out any underlying issues.

What do readings above 1.2 mg/dL for Total Bilirubin - TBIL mean?

Elevated Total Bilirubin levels above the normal range may indicate:

  1. Liver disease: Including hepatitis, cirrhosis, or other liver disorders
  2. Bile duct obstruction: Blockages in the bile ducts can prevent bilirubin excretion
  3. Hemolytic anemia: Rapid breakdown of red blood cells
  4. Gilbert’s syndrome: A harmless genetic condition affecting bilirubin processing
  5. Newborn jaundice: Common in newborns due to immature liver function

High levels may cause yellowing of the skin and eyes (jaundice). Further testing is usually required to determine the underlying cause.
