Liver Function Test: Bilirubin, Albumin, and Fibrinogen Profile (Serum)
This test measures key substances in your blood that help assess liver health, including bilirubin (a waste product from red blood cells), albumin (a protein made by the liver), and fibrinogen (a blood-clotting protein).
["This test helps doctors check if your liver is working properly or if there may be an issue like inflammation, damage, or disease."]

What This Test Measures
Bilirubin: This yellow pigment is produced when your body breaks down old red blood cells. High levels can indicate liver problems, gallbladder issues, or blood disorders. Albumin: A protein essential for keeping fluids in your blood vessels. Low levels may suggest liver disease or malnutrition. Fibrinogen: A protein involved in blood clotting. Low levels can signal liver dysfunction or bleeding disorders.
Why It Matters for Liver Health
Your liver performs hundreds of vital functions, including filtering toxins, producing proteins, and breaking down waste products. Blood tests like this one help identify early signs of liver damage, such as hepatitis, cirrhosis, or fatty liver disease, before symptoms appear.
When You Might Need This Test
Doctors may order this test if you have symptoms like jaundice (yellowing of skin/eyes), fatigue, abdominal pain, unexplained weight loss, or if you have a history of liver disease, alcohol use, or exposure to toxins.
Common Causes of Abnormal Results
Results may be affected by liver diseases (e.g., hepatitis, cirrhosis), blockages in bile ducts, certain medications, alcohol use, or genetic conditions. Other factors like malnutrition, infections, or metabolic disorders can also influence these levels.
Reference range
Adult: 136-145 mmol/LN/A
No special preparation required. Avoid fatty meals before the test if possible.
