What liver function test is done for jaundice?


In the realm of healthcare, understanding the intricacies of liver function tests is crucial, especially when it comes to diagnosing conditions like jaundice. For individuals experiencing symptoms indicative of liver dysfunction, comprehending the significance of these tests can aid in timely diagnosis and appropriate treatment. In this guide, we will delve into the specifics of liver function tests for jaundice , shedding light on what jaundice is, its symptoms, causes, diagnostic procedures, and available treatments.

What is Jaundice?

Jaundice, characterised by yellowing of the skin and the whites of the eyes, is a condition that arises due to an excess of bilirubin in the bloodstream.Bilirubin is a yellow pigment produced during the normal breakdown of red blood cells in the liver. When the liver fails to efficiently process bilirubin or when there is an obstruction in the bile ducts preventing the flow of bile, bilirubin accumulates, resulting in the characteristic yellow discoloration associated with jaundice.

What are the Symptoms of Jaundice?

The onset of jaundice is typically accompanied by a range of symptoms, serving as warning signs of underlying liver dysfunction. These symptoms may include:

  • Yellowing of the skin and eyes
  • Dark yellowing urine
  • Pale stools
  • Fatigue and weakness
  • Abdominal pain or swelling
  • Nausea and vomiting
  • Itching sensation on the skin

If you or a loved one experience any combination of these symptoms, seeking prompt medical attention is imperative for accurate diagnosis and appropriate management.

Causes of Jaundice

Jaundice can stem from various underlying conditions affecting the liver's ability to function optimally. Some common causes include:

  • Hepatitis (viral infections causing liver inflammation)
  • Alcoholic liver disease
  • Bile duct obstruction (due to gallstones, tumors, or strictures)
  • Cirrhosis (scarring of the liver tissue)
  • Hemolytic anemia (accelerated breakdown of red blood cells)
  • Gilbert's syndrome (a benign genetic condition affecting bilirubin metabolism)

Understanding the root cause of jaundice is pivotal in devising an effective treatment plan tailored to individual needs.

How is Jaundice Diagnosed?

Diagnosing jaundice involves a comprehensive evaluation of medical history, physical examination, and specialized tests aimed at assessing liver function and identifying underlying pathology. Key diagnostic procedures include:

  • Blood tests:
      Liver function tests (LFTs) measure levels of enzymes, proteins, and bilirubin in the blood, providing insights into liver health and function.
  • Imaging studies:
      Ultrasound, CT scans, or MRIs may be performed to visualize the liver and identify any structural abnormalities or obstructions.
  • Biopsy:
      In certain cases, a liver biopsy may be recommended to obtain a tissue sample for microscopic examination, aiding in the diagnosis of liver conditions such as cirrhosis or liver cancer.

Collaboration between patients and healthcare providers is essential throughout the diagnostic process to ensure accurate assessment and prompt initiation of treatment.

Liver Function Test for Jaundice

Liver function tests (LFTs) play a central role in the evaluation of jaundice and other liver-related disorders. These tests encompass a panel of blood assays designed to assess various aspects of liver function. Key components of LFTs include:

  • Alanine transaminase (ALT) and aspartate transaminase (AST): Enzymes are released into the bloodstream when liver cells are damaged or inflamed.
  • Alkaline phosphatase (ALP) and gamma-glutamyl transferase (GGT):Enzymes indicative of bile duct obstruction or liver damage.
  • Bilirubin: Elevated levels suggest impaired bilirubin metabolism, a hallmark of jaundice.
  • Albumin and total protein: Measures of liver synthetic function.

By analyzing these markers, healthcare providers can gain valuable insights into liver health and tailor treatment strategies accordingly.

Treatment for Jaundice

Treatment for jaundice hinges upon addressing the underlying cause while managing symptoms to promote recovery and prevent complications. Depending on the etiology of jaundice, interventions may include:

  • Medications: Antiviral drugs for hepatitis, corticosteroids for autoimmune hepatitis, or medications to alleviate symptoms such as itching.
  • Lifestyle modifications: Abstaining from alcohol, maintaining a healthy diet, and avoiding hepatotoxic substances can help support liver function.
  • Surgical intervention: Procedures such as cholecystectomy (gallbladder removal) for gallstone-related obstructions or liver transplantation for end-stage liver disease may be necessary in certain cases.
  • Supportive care: Adequate hydration, nutrition, and rest are essential components of supportive care to facilitate recovery and promote overall well-being.


In conclusion, liver function tests serve as invaluable tools in the diagnosis and management of jaundice, offering valuable insights into liver health and function. By understanding the significance of these tests and collaborating closely with healthcare providers, individuals can take proactive steps towards preserving liver health and mitigating the impact of liver-related disorders. If you or someone you know exhibits symptoms of jaundice, seeking timely medical evaluation is crucial for timely diagnosis and optimal outcomes. Remember, prioritising liver health today can pave the way for a healthier tomorrow.
