Serum Bilirubin Test (Total & Direct) in Hisar

What is the Serum Bilirubin Test?

The serum bilirubin test measures the amount of bilirubin in your blood. Bilirubin is a yellowish pigment produced when red blood cells break down. The test helps evaluate how well your liver, gallbladder, and blood cells are functioning.

Parameters Measured

Why is it done?

• Routine health check‑ups
• Investigation of jaundice, dark urine, pale stools, or unexplained fatigue
• Monitoring liver disease, hepatitis, cirrhosis, or bile duct obstruction
• Assessing the effect of medications or toxins on liver function

Early Detection

This test can help identify signs of liver dysfunction, bile duct blockage, or hemolytic disorders, but it does not diagnose a condition on its own. A doctor interprets the result together with symptoms, history, and other investigations.

What abnormal results mean

• High bilirubin may indicate liver disease, bile duct obstruction, hemolysis, or certain inherited disorders. Many factors—such as dehydration, recent blood loss, or certain drugs—can also raise levels.
• Low bilirubin is uncommon and usually not clinically significant; it may reflect very low red‑cell turnover or laboratory error.

Who should consider this test?

• Individuals with jaundice or yellowing of the skin/eyes
• Patients with chronic liver disease or hepatitis
• Those experiencing unexplained fatigue, dark urine, or pale stools
• People on medications known to affect liver function

Quick Takeaway

The serum bilirubin test measures liver health and red‑cell breakdown. It is a useful tool for detecting liver or bile duct problems early, but results must be interpreted by a healthcare professional.

Preparation

• Fasting: No fasting required for a bilirubin test. If you are also having a fasting blood glucose or lipid panel, fast for 8–12 hours.
• Medication: Continue your usual medications unless your doctor advises otherwise. Some drugs (e.g., rifampicin, phenobarbital) can affect liver enzymes but not bilirubin directly.
• Hydration: Drink plenty of water the day before; avoid excessive alcohol for 24–48 hours prior.
• Procedure: A healthcare professional will draw 5–10 mL of blood from a vein in your arm using a sterile needle. The process takes about 5 minutes and may cause a brief pinch.
• After the draw: Apply gentle pressure, keep the arm still, and avoid heavy lifting for a few hours.
• Follow‑up: Bring the sample to the lab within the specified time (usually 2–4 hours). If you have any questions, confirm the exact instructions with your doctor or the lab.
