Bilirubin
Understanding Bilirubin and Its Implications in Routine Blood Work
When you receive the results of your routine blood work, you may notice a term called "bilirubin" and wonder what it means and why it matters. Bilirubin is a yellowish pigment produced by the breakdown of red blood cells in the body. It plays a crucial role in understanding your liver health and can indicate various conditions when its levels are elevated.
What is Bilirubin?
To understand bilirubin, let's start with its origin. When red blood cells complete their life cycle, they are broken down in the spleen and liver. Bilirubin is a byproduct of this breakdown process. It is initially formed as "unconjugated bilirubin," which is insoluble in water and must be processed by the liver to become "conjugated bilirubin," which is soluble and can be excreted in bile.
Why Does Bilirubin Matter in Blood Tests?
In routine blood work, doctors measure the levels of bilirubin to assess the health of your liver and determine if there are any issues with the breakdown of red blood cells.
Common Causes of Elevated Bilirubin
Now, let's explore some of the common reasons why bilirubin levels might be higher than normal in your blood test results:
What Should You Do if Your Bilirubin Levels are Elevated?
If your blood work shows elevated bilirubin levels and this is a new condition, your doctor will likely investigate further to determine the underlying cause. This may involve additional tests such as liver function tests, imaging studies (like ultrasound or MRI), or specific blood tests for hepatitis viruses. If however your records show a history of mildly elevated fluctuating bilirubin levels in the past then a presumptive diagnosis of Gilberts syndrome will likely be made with no further testing needed.
Treatment will depend on the underlying condition causing the elevated bilirubin. For example, if it's due to a liver infection, antiviral medications may be prescribed. If gallstones are the cause, surgery may be necessary to remove them. As mentioned above, if Gilberts is the diagnosis then no treatment is required.
In conclusion, understanding bilirubin and its implications in routine blood work may be important for monitoring your liver health and detecting other potential underlying conditions. If you have any concerns about your blood test results or bilirubin levels, don't hesitate to discuss them with your healthcare provider. Early detection and management of liver-related issues can lead to better outcomes and overall health.

Common Causes of Elevated Bilirubin
Now, let's explore some of the common reasons why bilirubin levels might be higher than normal in your blood test results:
- Genetic Conditions: Far and away, the most common reason for an elevated bilirubin level in otherwise healthy individuals is Gilbert syndrome. This is a genetic condition which can cause mild elevations in bilirubin levels but it is harmless and not associated with any underlying liver disease.
- Gallstones: These are hardened deposits of bile that can block the flow of bile from the liver, causing bilirubin to accumulate.
- Liver Infections: Viral infections like hepatitis A, B, or C can cause inflammation and damage to the liver, affecting its ability to process bilirubin.
- Alcohol Abuse: Excessive alcohol consumption over time can lead to liver damage (cirrhosis), which impairs bilirubin metabolism.
- Medications: Some medications, such as certain antibiotics, antifungals, and chemotherapy drugs, can affect liver function and increase bilirubin levels.
- Hemolytic Anemia: This is a condition where red blood cells are broken down too quickly, leading to an increase in bilirubin production. Causes can include autoimmune disorders, infections, or certain medications.
